FAQ - The most important questions and answers regarding SpaBalancer

We have compiled the most important questions and answers regarding SpaBalancer. The answers open up as long as you select a question. In this way, we hope that we are able to bring the product closer to you. If you have any additional questions, please use our contact form.

What does SpaBalancer contain and how does it work? -- F001

SpaBalancer consists of a mixture of natural minerals. These minerals have the ability to encapsulate foreign substances at the molecular level. The encapsulated contaminants are clumped together and then filtered out.
The impurities may be bacteria and other microorganisms. Calcium, manganese, and iron is encapsulated as well. Encapsulation also occurs with urea, dander and other larger particles.

Bacteria and micro-organisms – SpaBalancer is not a biocide. It encapsulates bacteria. This encapsulated bacteria is then cut off from nutrients, which halts their metabolism and prevents them from dividing. This makes them harmless and rapidly filters them out through clumping. Bacteria always come into contact with water when using the hot tub. Some bacteria are very dangerous. If water is heated to 37 degrees Celsius and a rich supply of nutrients is present, many bacteria can double in number every 30 minutes. This means that hot tubs are usually unsafe with respect to your health. SpaBalancer encapsulates any bacteria present within a few minutes, which prevents proliferation. Because encapsulation is a physical process, bacteria cannot build up immunity and there are no dangerous waste products which might otherwise result from chemical reactions, e.g. from the use of chlorine.

Legionella – Legionella bacteria are highly resistant to conventional disinfection. They often live within amoebae and as a result can be difficult to reach with traditional disinfectants. Once again, the principle of encapsulation works wonderfully and Legionella no longer pose a danger.
In addition to bacteria and microorganisms, many other substances are present in water that pollute it. These include e.g. urea, sweat, soaps, shampoos, dandruff and much more. Everyone who has ever been in a hot tub knows how clean his or her skin is afterwards. Numerous toxins from the skin are excreted through the activated lymphatic system and end up in hot tub water.All these substances are inadequately removed with conventional disinfectants. For filter cartridges, most substances are too small to be filtered out. The consequences are often very streaky, clouded water that typically foams and carries a variety of unsavory particulate matter with it. Since SpaBalancer encapsulates all these substances and clumps them together, they can be filtered out very effectively and the water always has the same crystal-clear spring-water quality.

How often must I change the water in the whirlpool? -- F002

When using chlorine or other oxidizing agents to disinfect water, dozens of chemical waste products are formed. We know that some of them are carcinogenic. With most of these waste products we do not know if they are harmful to health, or if so, how harmful. Furthermore the disinfecting performance of chlorine and other disinfectants is reduced if too many waste products have accumulated in the water. This is why the water should be changed every two months.

SpaBalancer works by encapsulation at a molecular level. No oxidisation processes are produced, so no chemical waste products can form and accumulate. Therefore the water does not have to be changed.

However, we still recommend an annual water change, so that any deposits which may have formed in the pipe system can be cleaned with SpaBalancer System Flush as the water is changed.

I refilled the whirlpool and added SpaBalancer to the fresh water. The water turned a milky colour - why is that? -- F003

This is a normal reaction. As SpaBalancer starts to work, it encapsulates impurities in the water. This is what causes the discoloration. This is especially true of whirlpools that have been in operation for some time, because SpaBalancer dissolves biofilm which has formed in the tubing. Please clean the filter the following day and increase the filter's running time. The cloudiness usually disappears within a day. In particularly severe cases, the water may remain cloudy for up to three days.

detail page

Do I need an ozonator for SpaBalancer to work? -- F004

Although SpaBalancer would work without an ozonator, we always recommend the use of an ozonator since this technique has been shown to be effective and kills organisms very safely and efficiently. 


detail page

Do I need to adjust the pH value when using SpaBalancer? -- F005

SpaBalancer works at any pH level. However, please make sure that your pH level remains in a range of 7.0 to 7.8, since a pH level that's too high or too low can damage your hot tub.
Please note that the pH level can rise sharply the first few weeks after refilling your hot tub. This is the water's natural reaction to being heated up and to turbulence, and is not caused by SpaBalancer. Following this period, the pH usually levels off in its natural range of 7.0-7.8. If this does not happen, please lower the pH with a pH reducer.
Measure your pH level at least once per week to detect and correct any potentially excessive pH values. You can use any commercial pH lowering/raising products for this.

Can you use your spa with SpaBalancer in it if you have lung disease? - F006

As far as this concerned, until now our customers have had only positive experiences with SpaBalancer. Below is a testimonial by one of our customers:
For people with lung problems, SpaBalancer is the only way you can enjoy your hot tub (this goes for people with bronchitis, asthma, whooping cough, and COPD too). Chlorine and similar products only aggravate the disease. SpaBalancer is also great for folks looking to maintain their tan long after they've returned from vacation, since chlorine bleaches your skin in no time. I think it's appropriate here to point this out just a bit more. Also, the water is softer and your skin doesn't feel dried out while you're in the spa or afterwards. It's super easy to use. The only thing that requires a bit of effort is the initial filling. Every now and then I add some SpaBalancer Ultrashock. Using both products gives you really excellent water quality for approximately 1 year (go ahead and test it).

Best wishes from Neumarkt

Can I use a sand filter with SpaBalancer? -- F007

Can I use a sand filter with SpaBalancer or can I only use a cartridge filter, because of the prescribed 2-weekly filter disinfection?
In principle, using a sand filter is no problem. However, a sand filter should also be cleaned and back-flushed regularly.
SpaBalancer encapsulates foreign matter on a molecular level. The encapsulated contaminants end up in the filter. If they are not regularly removed, they may begin to rot, creating pollution which will reduce the efficiency of the filter. This can result in cloudy, unpleasant-smelling water.We highly recommend closing the valves before back-flushing and putting Ultrashock in the sand filter - approx. 25 ml per litre of filter capacity. The Ultrashock should remain in the filter for at least 12 hours before proceeding with the back-flush.
Ultrashock is a very powerful oxidant which also quickly and effectively destroys biofilm, so it is ideal for cleaning sand filters.

My water has a slightly pale green colour, not blue. What’s causing this? -- F008

A slightly pale green colour of water is actually its natural colour. Most of the waters of Europe are not blue, but green. Blue water is due to the presence of salt or chlorine. Chlorine gives water a blue tint. Most water providers chlorinate tap water. So it’s possible, after filling the whirlpool, that the water looks blue in colour. When the chlorine disappears, so does the blue colour, and the natural colour of the water is revealed.
Another cause of the green discoloration can be a mineral dispenser (silver ions) such as Nature2 for example.

Only in the case of a dark green colour should UltraShock be employed because the water has then most probably not been adequately cleaned.

When used, nozzles form a spray which irritates the respiratory tract. What is it, and what can I do about it? -- F009

If the respiratory tract is getting irritated, then deposits of other chemicals insufficiently encapsulated by SpaBalancer are building up in the pipes. SpaBalancer releases deposits and encapsulates them. SpaBalance can however have encapsulation issues with some chemical residues.
First, I’d recommend adding Ultrashock to the water every two to three days (approx. 40 ml/1000 Liter). Ultrashock oxidizes a lot of contaminants. If that doesn’t help, I would advise you to perform a thorough cleaning of the whirlpool using System Flush.

Is SpaBalancer completely healthy to use? A kinesiological test. -- F010

Kinesiology test of whirlpool water maintained with SpaBalancer I came across SpaBalancer while searching for skin-friendly water care for the whirlpool we’re planning, and saw that it has a lot of positive feedback on the internet.
Since I’ve already kinesiologically tested tap water and bottled water for its impact on the body for a number of individuals, I wanted to assess the water quality of a whirlpool. 

I’ve previously tested the quality of whirlpool water treated with chlorine and reject it as totally unsatisfactory for us. In order to assess the water quality of a whirlpool maintained with SpaBalancer and its effect on the body, I had a bottle of whirlpool water sent to me. According to information from the owner, this water was in the whirlpool for about 6 months.

The central issue when testing the water was: what is the effect of water on the energy state of individual organs? To determine the energy status of the organs, I employ kinesiology testing with the arm. Here, one uses the change in tension of the musculature as an indicator of change. The easiest way to determine the change in tension is by way of the arm muscles. The area of the body to be tested is touched, the brain transmits thought information and a potential change in the musculature is simultaneously physically tested.

How is kinesiological testing explained? Every thought constitutes information. Any such information immediately triggers a variety of electrical and chemical reactions in the body. These reactions have a direct effect on the tension state of the body’s entire musculature.

Substances such as water also represent information. This information can affect the body’s field of tension and consequently also affect the body's musculature. Using the test subject, I examined the following organs and glands: thyroid, lung, thymus gland, liver, gall bladder, stomach, pancreas, spleen, small intestine, large intestine, genital organs, skin.

The energy state of the organs and glands represents a snapshot in time and can change rapidly. Still, it possesses a continually recurring personal level, comparable to the fitness level of a person with its individual ups and downs. If the personal energy level of an organ is permanently low, this leads to a state of unwellness and, if it remains that way for weeks, months or years, leads to physical problems and changes. I first investigated the momentary energy state of the organs and glands without whirlpool water. Next, I placed the whirlpool water on the hand of the test person and waited a while for the information from the water to be absorbed by the body. I then re-tested every organ and every gland for changes in energy state.

Results: Wholly positive. I was unable to perceive a deterioration in the energy state of any of the organs. This is an exceptionally good result, and one that I had not expected. This has prompted me to order a whirlpool and to treat the water with SpaBalancer. I have yet to test SpaBalancer’s affect in our own whirlpool, since it’s only scheduled to be installed in 3 months. I’ll be happy to provide feedback on the effect of our own whirlpool water at that time.

Brown rim at the waterline. -- F011

I’ve been using SpaBalancer for six weeks. The water is crystal clear. Now on the acrylic at the waterline a brown rim has formed. What is it, and what can I do about it?
The brown rim consists of encapsulated deposits that have collected. This can occur in the beginning because the whirlpool is usually used excessively at first. The brown rim is very easy to clean away using a microfiber cloth. Just to be sure, I’d also add 40 ml of Ultrashock (per 1000 litres) to the water. Repeat the application of Ultrashock should the brown rim reappear.

Is SpaBalancer also effective against legionella in a jacuzzi? -- F012

Legionella bacteria multiply rapidly in hot tubs and pose a serious health threat. Our SpaBalancer system is also 100% effective against Legionella. Just so you're sure that what we're saying is true, Graner & Partner tested the SpaBalancer system and you can see the result here.

Is UltraShock a chemical agent or a biological one? -- F013

UltraShock is a chemical oxidizing agent. In that sense it works similarly to chlorine or bromine, for example. But unlike chlorine and bromine, it has no side-effects that are hazardous to health. That’s why the basic ingredient of Ultrashock is also approved for disinfecting drinking water. And in Germany, drinking water is classified as a foodstuff and is therefore subject to the stringent German laws governing food.

When bromine or chlorine is used as an oxidizing agent, trihalomethanes are produced, as well as many other substances which have not yet been investigated. These substances are by-products produced when chlorine combines with amino acids (sweat, organic products). Trihalomethanes can also cause cancer and damage foetuses, which is why chlorinated water should be avoided at all costs during pregnancy. All these new substances which are produced are known as chloramines or combined chlorine.

UltraShock does not combine with amino acids. Therefore it does not produce any trihalomethanes or other dangerous by-products either.

Unlike chlorine, UltraShock is also harmless to the organism. In order to understand this, one needs to know that the process of oxidation involves a removal of electrons. Chlorine and UltraShock as well are so-called ‘electron thieves’: they steal electrons from the bacteria, which subsequently die. Because it is the electrons that hold everything together. If you remove the electrons from an object, it disintegrates.

There are differing strengths of oxidation. To take oxygen as an example, it has an oxidizing strength of 1.3 volts. Aerobic and basic bacteria in the body are destroyed above a level of 1.45 volts. Nearly all the essential bacteria in the human body are aerobic bacteria. Aerobic means that they use oxygen to metabolise.

Chlorine, bromine and also ozone have an oxidizing strength above 1.45 volts. In the case of ozone it is 2.07 volts. They therefore destroy all bacteria. But what is good for water is not good for the human body. Each time we bath, the human body takes in several hundred millilitres of water through the skin. So bacteria on the skin and in the body are killed off. This also explains the prevalence of chlorine allergy – simply too many beneficial skin bacteria have been destroyed. This means that the skin can no longer effectively fulfil its function as the biggest detoxifying organ in the human body.

UltraShock has an oxidizing strength of 0.95 volts. And all pathogenic bacteria which are anaerobic and acid also have an oxidizing strength of 0.95 volts. This means that pathogenic bacteria which cause diseases and metabolise without oxygen in an anaerobic environment are killed off by UltraShock. And only those bacteria. The aerobic bacteria so essential for the body are not destroyed. Their oxidation potential is too high for UltraShock. So swallowing bathwater containing UltraShock is not harmful to health.

Unlike chlorine, UltraShock is also effective against viruses and unicellular organisms. For this reason UltraShock is highly effective against legionella.

Because UltraShock, unlike chlorine, removes 5 electrons at once from bacteria, their DNA is also destroyed. This means that bacteria cannot build up resistance against UltraShock. In the case of chlorine, bacteria can become resistant. The bacteria can wrap themselves in biofilms which they produce themselves, making them inaccessible to chlorine. UltraShock speedily destroys these biofilms as well.

Is the SpaBalancer system safe? Can I go in the whirlpool without worrying about bacteria? -- F014

The warm water in the whirlpool is an ideal growth medium for dangerous bacteria. The number of bacteria in the whirlpool can double every 30 minutes. This leads to very contaminated water in the shortest time. The consequence can be skin rashes or other illnesses. For this reason it is important that the water treatment product reliably stop bacterial reproduction. To be sure that you are protected from harmful bacteria we have submitted our SpaBalancer system to microbiological testing against the most dangerous bacteria. And the results have been 100% positive. You can see the microbiological test results here.

A rough, hard layer has formed on the acrylic. What is this? -- F015

This rough hard layer can also be powdery. This is a layer of limescale. In the case of hard water, the water may contain hardening substances such as calcium and magnesium. These mineral deposits are present in dissolved form. At an elevated pH higher than 8.5 these hardening agents can turn into limescale, which then settles on surfaces and coats them. If you have a difficult time removing the coating, I recommend lowering the pH to 5.5 for one to two days. The acidic water will then dissolve the limestone, after which it can easily be wiped off or will disappear by itself.
What should you do to prevent these deposits?
1) Keep the pH of the water under 8.5. Limescale only forms at a pH of 8.5 or higher.
2) If you have hard water, fill the hot tub with SpaBalancer SoftWater Filter. The SoftWater Filter will soften the water.
3) After filling, add some SpaBalancer SoftWater to the water.

What should I pay special attention to when filtering and cleaning filters? -- F016

Modern cartridge filters are made of a special fabric that has millions of tiny passages. These passages trap and hold back dirt. Improper cleaning can result in bacteria developing in the fabric and forming a biofilm which protects them. Fats, oils and skin cells than become a food source for the bacteria. When this happens, the filter turns into a source of pollution for the water. In addition, contaminated filters lead to higher electricity consumption by the filter pump and shorten the life of the filter pump.

Please consider the following when filtering and cleaning filters:
1) Filter the water for at least 6 hours a day.
2) Clean filters every 2 weeks. The time interval may vary depending on the frequency of use and water contamination. Testing by feel: if slimy deposits have collected in the ribs of the filter, the filter needs to be cleaned.
3) Always clean the filter with a filter cleaner. Rinsing is insufficient because the deposits which accumulate in the capillaries of the filter fleece are partly fatty and difficult to rinse out.
4) Let the filter dry out thoroughly after cleaning.5) In case filters get extremely dirty and are no longer white, they can be soaked overnight in a solution of SpaBalancer UltraShock (approx. 20 ml per 10 l water) and afterwards they will look like new.
6) Always keep a spare filter so you can use it for the hot tub while you are cleaning the other filter.
7) Do not use sponge filters (Microclean filters). These filters can not be cleaned and so become a breeding ground for bacteria.
8) Dispose of filters and replace them with new ones after a year running time.

I recommend the use of our SpaBalancer FilterClean. It dissolves deposits very well, does not foam and is made from environmentally-friendly herbal substances. It contains a special herbal substance which prevents the unpleasant odour which sometimes occurs with used filters. For rinsing, I suggest the SpaBalancer filter-cleaning head - it really is amazingly effective. For occasional cleaning in between, we recommend SpaBalancer Instant FilterClean.

Can I put salt products into the water if I use SpaBalancer? -- F017

Yes, that's no problem. You can put bath salts or other types of salt into the water.

Thorough cleaning of the spa -- F018

Sometimes problems crop up that cannot be resolved. Deposits and biofilm may settle in pipes, especially in new spas, but also in spas have been empty for long periods of time or spas in which chlorine was used during operation.
New spas
New spas are filled with water at the factory in order to test for leaks. Fresh water is not used in these tests. Rather, the water employed in the test is repeatedly used and is therefore contaminated with dirt and bacteria. Cleaning agents, solvents, glues and dirt can also enter pipes during assembly. Spas can never be emptied 100%. Several liters remain in the pipes for weeks, where the liquid festers and forms biofilm.

Spas that have been empty for long periods
Again, the problem here is the water remaining in the pipes (up to 50 liters at times). This water begins to fester and become moldy.

Spas that are repeatedly disinfected with chlorine or other disinfectants
Bacteria have developed an ingenious strategy for survival. They form a slimy coating in which they wrap themselves. This coating is called biofilm, and sticks to the inside of pipes. Chlorine is unable to penetrate this coating. This means that the bacterial population can multiply rapidly even in a well-chlorinated spa.

This biofilm, along with deposits and to an extent mold, can sometimes initially lead to problems when operating a spa and using SpaBalancer. SpaBalancer slowly detaches these contaminants from pipes. However, this also overloads SpaBalancer when the product is initially used. In some instances, it may take up to three months before SpaBalancer has properly cleaned a spa. To expedite this process, we recommend a thorough cleaning of your spa.

To thoroughly clean your spa:
Take one bottle of SpaBalancer SystemFlush for a spa. One bottle of SpaBalancer SystemFlush is adequate for a spa that holds 1,500 liters of water. In particularly tough cases, you can also double the amount used.

1. Remove filters
2. Shake the bottle well
3. Turn on all pumps and pour the bottle of SpaBalancer SystemFlush into the water
4. Allow SpaBalancer SystemFlush to work overnight
5. The next day, turn on your pumps for another 20 minutes
6. Empty the spa
7. Rinse pipes thoroughly using a nozzle and a garden hose
8. Fill the spa with fresh water

To ensure that all broken up biofilm and bacteria are reliably killed, add 150 ml of SpaBalancer UltraShock for every 1,000 liters of fresh water. Allow the UltraShock to work overnight, then empty the spa the next day. You can now be sure that no residual deposits and no more dirt remain in the pipes of your spa.

I start coughing and experience shortness of breath when I use the hot tub. What causes this? -- F019

Biofilm forms in the pipes of many newer and older hot tubs. This biofilm is produced by bacteria. The film has a soft to partially rock-hard consistency and is virtually impossible to remove from the walls of the pipes. The biofilm also traps numerous chemicals that have been used to treat the water.
You can use SpaBalancer and UltraShock to dissolve and remove this biofilm. Ultrashock by itself can loosen and dissolve biofilm very quickly, and oxidizes the old chemicals contained in it. This may release fumes that can lead to coughing and shortness of breath. To remedy this, the hot tub should be subjected to a thorough basic cleaning. Following this basic cleaning, a little more than the recommended amount of Ultrashock should be used during the subsequent first few days.

I want to go away on holiday. What do I need to do? - F020

One of SpaBalancer's greatest advantages over other methods of treating water is its long-lasting effectiveness. As long as no dirt gets into the water, SpaBalancer doesn't get used up and keeps your water crystal clear.
Screw a freshly cleaned filter cartridge into the hot tub. Lower the water temperature as far as possible with the controls on the tub (most hot tubs have a minimum temperature of 15 or 25 degrees Celsius). Put double the usual weekly amount of SpaBalancer into the hot tub. That's all you have to do!
When you come back from your holidays 6 weeks later, you will see that the water is crystal clear.
Last winter I left my hot tub like that for 3 months and the water was still crystal clear afterwards.
If you want to play it really safe, then give the water a shock treatment with SpaBalancer UltraShock when you come back from your holidays (50 ml per 1000 litres of water).

Is SpaBalancer skin-friendly? -- F021

Many people complain of skin problems when using their hot tubs. These skin problems are almost always caused by the disinfectants used. Our SpaBalancer cleaning system is 100% skin-friendly – we’ve had it tested.
The test was conducted by the proDerm Institute for Applied Dermatological Research.
For the study, 22 subjects were tested against 5 different samples over a period of 6 days.
Sample 1 - Test series A = Pure tap water
Sample 2 - Test series B = Sodium Dodecyl Sulfate (dilution 0.3% - positive sample. All skin types react to this substance)
Sample 3 - Test series C = SpaBalancer (dilution 40 ml / 1000 liters)
Sample 4 - Test series D = UltraShock (dilution 40 ml / 1000 liters)
Sample 5 - Test series E = mixture of UltraShock and SpaBalancer (1:1 mixture)
Study results: test subjects showed no reaction to either SpaBalancer, UltraShock or the mixture of SpaBalancer and UltraShock. Consequently, this indicates that the skin’s toleration of SpaBalancer and Ultrashock is identical to that of fresh drinking water.

A slippery film has developed on the walls and the floor of the whirlpool. What is going on? -- F022

The slippery film can occur especially early on. Especially at the beginning period, SpaBalancer can be somewhat overburdened. The mechanism of action of SpaBalancer consists of encapsulating foreign matter at the molecular level. This encapsulated foreign matter is then clumped into somewhat larger units and filtered out of the water by the filter. Especially during the initial period, there can be very large amounts of foreign matter in the water. These may include:
- naturally occurring minerals in the water
- fats, oils, skin scales (especially in the early period, the lymphatic system in the skin is stimulated to work harder by the warmth and the massage action, and toxins, fats and contamination that has been stored in the skin all year is now excreted from the skin into the water and must be encapsulated by SpaBaancer.)
- Biofilm deposits in the tubing are dissolved and encapsulated. (These deposits always develop in whirlpools treated with customary disinfectants such as chlorine. These biofilms may even be present in a new whirlpool. This is due to the residual water in the tubing which may not have been fully removed during test operation at the factory.)
- Excessive use during the initial period. People are especially likely to use a new whirlpool every day. Later, the intensity of use tends to diminish somewhat. You can wipe off this slipper film with a cloth and increase the filtration time. Clean the filter thoroughly. Increase the amount of SpaBalancer by about 30 to 40 percent.
You can get rid of this slippery film even more rapidly and thoroughly by using UltraShock. In the evening, add about 50 ml/1000 liter UltraShock in the water.
Repeat this procedure during the following days until the slipper film has disappeared. Normally, it will already be gone after the first addition of UltraShock.

SpaBalancer and water hardness -- F023

In general, SpaBalancer works well regardless of hard the water is. However, there are a few points to be noted:
Over long periods of time, SpaBalancer makes the water very soft. It removes the substances which create hardness in water.
In the short term, despite using SpaBalancer, limescale deposits may form in the whirlpool.
Certain hardness-forming minerals in the water can lead to musty smells.

What is water hardness and what effect does it have?

All water contains substances which may create hardness. These are mineral substances which are dissolved in water in the form of ions. The two most important of these are calcium ions and magnesium ions, but there are many other hardness-forming elements in water. It depends on where the water comes from.
The more hardness-forming elements are in the water, the harder the water will be.

At normal water temperature and at pH 7, these elements remain dissolved in the water, but they start to change as soon as the water temperature increases and the pH value climbs to over pH 8.5. They are transformed into insoluble lime or soap scum. These accumulate as a rough deposit on the surface of the whirlpool.

How hard should the water be?

The ideal water hardness is about 100 ppm. This can be measured with our test strips. 

What should I do if the water is too hard?

If the water is too hard, you should add our SoftWater Filter to your whirlpool. It contains salts and replaces hardeners with sodium ions. The SoftWater Filter can be reused several times. (You will already know the principle from your dishwasher. Salt is added to reduce the hardness of the water.)
I also recommend the use of SpaBalancer SoftWater. This is a completely harmless substance which binds hardness-forming minerals  in such a way that they can no longer be converted into limescale. 

What should I do when limescale has already formed?

If a rough layer has already formed on the surface of the whirlpool, you should lower the pH value of the water to 5.0 for about 2 days, which makes the water acidic. Acidic water has a natural tendency to become neutral again by absorbing alkaline minerals, thus making the rough limescale deposits completely disappear. Afterwards, readjust the pH to 7.0 and add SpaBalancer SoftWater to the water to prevent limesscale forming again.

Didn't you write before that SpaBalancer makes the water soft?

Yes, that is correct. SpaBalancer encapsulates hardeners so they can be filtered out - but that is a slower process. Especially at the beginning, there are too many hardeners in the water, and SpaBalancer is overloaded.
In the long term, SpaBalancer will remove all excess hardening substances, protecting your heater against limescale deposits and the resulting damage (limescale deposits stop the heat from dissipating and the heating element burns out). Limescale forms especially quickly on warm heating elements. 
SpaBalancer also prevents the formation of unsightly hard-to-clean rings of lime/fat just above the water line. 

Can the hardness-forming minerals create musty smelling water?

Yes, they can. SpaBalancer encapsulates these hardeners, but if they are not thoroughly filtered out, they can start to decay. For example, decaying calcium can smell mouldy. If you have musty-smelling water, you should increase the filter run time to at least 6 hours a day and cleanse the filter very frequently and thoroughly with a filter cleaner. It is also recommended to add SpaBalancer SoftWater to the water.

We do not use our whirlpool continuously. It is located in a vacation house and is only used twice a year, each time for 2 to 3 months. -- F024

This is a problematic situation. The whirlpool is drained at the end of the vacation period and then it sits for several months without disinfection. The residual water - as much as 50 liters - in the piping cannot be drained. It begins to putrefy. The bacteria count in this water explodes and biofilms form that are difficult to remove.

When the whirlpool is filled again, the fresh water is immediately contaminated with the bacteria and dirt.

In order to prevent this scenario, I would recommend a shock treatment with UltraShock before the old water is drained. Add 100 ml UltraShock per 1000 liters of water in the whirlpool and let it work overnight. In this way, all bacteria that may be present will be killed and the water that remains in the piping will continue to be strongly disinfected. For the time being, no bacteria can grow there.

When refilling the whirlpool, I would recommend basic cleaning of the whirlpool with SystemFlush. Should any biofilms have formed in the piping, it will be removed by the basic cleaning.

Can I use SpaBalancer even in a 10,000 litre swim spa? -- F025

The cleaning of the water in a swim spa is in one sense easier to achieve, and in another sense harder to achieve than with a jacuzzi. It is easier because the water temperature is lower. Also the amount of grime that ends up in the water is lower because, as a rule, it is only used by a few people.
In summer the swim spa is left open for a longer time and kids splash around in it. This means a lot more grime gets into the water compared to a Jacuzzi. For this reason, we have specified relatively high amounts of SpaBalancer and UltraShock in our water maintenance manual. Those amounts are 100ml SpaBalancer and 100ml UltraShock per week. If the swim spa is used by two people 3-4 times a week who shower beforehand, and the swim spa is covered when not in use, then the amount of SpaBalancer and UltraShock can be lowered. I know people who manage with 50ml SpaBalancer and without UltraShock. Another large factor here is whether the swim spa has additional ozone or UV disinfectant. These also reduce the amount of SpaBalancer required.


detail page

Can SpaBalancer also be used for a wooden hot tub with a stainless steel oven and a sand filter system? -- F026

Yes, SpaBalancer can also be used for wooden hot tubs, provided that the sand filter is regularly cleaned with UltraShock and back-rinsed. You can read how to do that by referring to question number 7.

What is Biofilm and what can I do to avoid it? -- F027

Bacteria are relatively harmless when they occur on their own. They can be killed off very easily using disinfectant. This is why you produce a type of mucous that entraps them. The Biofilm.

1) Biofilm is a thin, viscous layer of organic substances that clings to the inner walls of plumbing. - The adhesion prevents it from being rinsed away.2) Biofilm consists of polysaccharides. These polysaccharides are insoluble in chlorine or bromine.
3) Grime (e.g. soap residue, body oils, etc.) as well as hard water deposits (e.g. calcium, lime, etc.) also become trapped in the biofilm.
4) Biofilm occurs in various forms from thin and viscous to stone hard. That is a question of age.
5) Living in the biofilm are bacteria, amoebas, algae, and fungi that are resistant to disinfectants
6) At the boundary layer of the water, parts of the biofilm and/or bacteria etc. get deposited into the water time and time again.
7) Since the biofilm is resistant to chlorine, it grows incessantly.
8) Biofilm is capable, for example, of absorbing and metabolizing chlorine. So, bacteria can even feed off of chlorine (i.e. "chlorine demand", which can cause a rapid decline in chlorine in the Whirlpool).
9) Biofilms are resistant to UV disinfection (ultraviolet light) and silver ion disinfection as well.

Here are a few pictures of some biofilm found in Whirlpool plumbing that was disinfected for a year and a half using chlorine. The deposits containing layers upon layers of grime and other calcifications are easily visible to the naked eye.




Biofilm can also appear in new Whirlpools. These biofilms form due to leak tests conducted in the factory with “compromised” water (i.e., water used over and over again). Upon emptying, up to 40 liters of water can remain in the internal plumbing. There it putrefies and forms into biofilm.
Those quote-on-quote "new" Whirlpools can sit for weeks in transit in hot containers (in the summer) and then be kept in storage warehouses or put on display somewhere before it comes to you. For that reason, you should always use SpaBalancer UltraShock right when you get a new Whirlpool.

SpaBalancer prevents the formation of biofilm due to dirt and bacteria and can entrap and filter away oils and hard water deposits as well. It can also stunt and halt the grown of biofilm that has already formed. Nonetheless, SpaBalancer was not designed to remove biofilm.
With existing biofilm, SpaBalancer could potentially cling to the biofilm and entrap it against the pipe wall. Hence, substantial flaking could occur if the water flow strips off shards of the entrapped biofilm.To remove biofilm, you can use UltraShock. UltraShock dissolves the polysaccharides existing in the biofilm. That can take a few weeks, however, if the biofilm is very old, solidified, and thick.When removing the biofilm, it is advised to start with a basic Whirlpool cleaning using SpaBalancer SystemFlush and UltraShock. Then, follow up with more frequent SpaBalancer UltraShock treatments until the biofilm itself has completely dissolved and disappeared.

I have lots of gel-like flakes in the water. What is it, and what can I do about it? -- F028

SpaBalancer encapsulates organic contaminants. This always happens fully automatically in the water if you add SpaBalancer. As long as these contaminants float in the water, they will be encapsulated and filtered out. This means that the water in the SpaBalancer system is maintained clear, and free of germs. However, if there are deposits on the inner walls of the pipes, SpaBalancer will try to encapsulate these deposits as well by settling on top of them. This forms a gel-like layer that can be up to 2-3mm thick. At some point, a portion of this covering is torn off by the flow of water into the piping. A chain reaction then occurs as the remaining coating is also torn off by the flow. This releases a lot of these flakes.

What can cause these deposits?
- Using a dosage of SpaBalancer and UltraShock that is too low
- Existing deposits from test water at the factory
- Existing biofilm from previous cleanings with chlorine, etc.
- Reactions between cosmetics and SpaBalancer
- Limescale that is clinging to the piping

How can I remove these deposits?
These deposits are very difficult to remove with chemicals. Still, the deposits are harmless. In the next 4 weeks, add as much UltraShock to the water as needed so that you always measure 0.5 ppm UltraShock content with the test strips. During this period, adding 40 ml of SpaBalancer per week is sufficient. Use a rubber band to fasten a pair of women’s stockings over the suction filters of the pumps to get the flakes out of the water. As a rule, the flakes only form one time and the situation won’t repeat itself. If you’re not able to remedy the problem using the steps above, please contact me. We will then perform an intensive basic cleaning of the spa tub.
Are these flakes dangerous? Since they are encapsulated, these flakes are not dangerous. The water is and remains clean. Nevertheless, just to be on the safe side I would regularly add UltraShock to the water. Make sure you add enough so that you consistently measure 5 ppm with the test strips.

How can I avoid these flakes?
1) Avoid underdosing of SpaBalancer and UltraShock
2) Make sure you’re not getting limescale buildup. Add enough SoftWater to the water and keep the pH below 8.0. If you have limescale, lower the pH value of the water to 5.0 until the limescale has disappeared.
3) For very hard water, we recommend you use a water softener when filling your spa tub.
4) Run filters for a sufficient amount of time – at least 6 hours a day – and clean them thoroughly and frequent with filter cleaner and a very strong jet of water.
5) Avoid using creams or cosmetics if you’re going to enter the water. If necessary, shower beforehand and do not use any moisturizing lotions. If you want to be sure about what you can use, proceed as follows: mix a small sample of the lotion or cream with SpaBalancer in a 1:1 ratio. If the lotion thickens and becomes creamy, then it’s not suitable.
6) As a precaution, the Ultrashock content can be maintained at 0.5 ppm and SpaBalancer can be reduced to 40ml per week.

Can I empty my outdoor whirlpool in winter? -- F029

I want to discontinue using my outdoor whirlpool for a long period of time. From experience we know that we only start using it again in spring – in March or, more likely, April. I don’t think it’s sensible to maintain the whirlpool at 37 degrees the whole time, which is why I'm considering two other options:
1.) Lowering the temperature to 16 degrees and then increasing it again in April.
2.) Completely draining the water and then refilling in April.
Which procedure would you recommend here?

I would prefer lowering the water temperature and leaving the water in the whirlpool with a reduced filter run time (about 3 hours per day). Why? There are two dangers when emptying a whirlpool. If residual water in the pipes or nozzles freezes, this can cause frost damage and the whirlpool could be damaged and start leaking. Over the winter, you can stop adding UltraShock. Adding approx. 50 ml of SpaBalancer to the water every 4 weeks will be enough. Also filter cleaning needs to take place only every 6 to 8 weeks, because no dirt is being brought into the whirlpool.
The second danger is the formation of biofilm. About 40 to 50 liters of residual water remain in the pipes following draining. You can never completely empty a whirlpool. This water can now begin to get putrid because bacteria are multiplying in it. If you drain the water, you should fill the whirlpool in spring, heat it up, and then perform a thorough cleaning with 1 bottle of SystemFlush and 1/2 bottle of UltraShock.

Can SpaBalancer UltraShock be combined with Aquafinesse products? -- F030

Is your UltraShock also compatible with Aquafinesse products? We want to get away from shock chlorination because of the extreme increase in the cyanuric acid content in the water. When the Aquafinesse has been all used up we could switch to your products. Aso, is there any kind of dispenser that would always keep the amount of UltraShock in the spa at 1 ppm?

You can use our UltraShock in combination with AquaFinesse. The will give you the following advantages:

- No more chloramines form
- Existing chloramines are destroyed
- No more cyanuric acid in the water
- The water is no longer corrosive to metals
- The water does not generate any fumes which destroy the plastic parts (cushions, nozzles, insulation cover)
- UltraShock also works very well at high pH values
- The skin and subcutaneous tissue are not damaged, unlike chlorine
- No carcinogenic trihalomethanes are formed
- Existing biofilms are penetrated and bacteria located therein are killed
- UltraShock is not reduced by heat. In contrast to chlorine, UltraShock remains effective in the water for a considerable period of time

UltraShock is a liquid. Therefore, you cannot dispense it with a dispenser. However, this does not present a problem. UltraShock is only reduced by organic dirt and grime, not by heat and not by swirling water. In contrast to chlorine, UltraShock remains stable in water for a very long time.

What should I do if I have too much UltraShock in the water? - F031

Hi SpaBalancer team,
There was a bad “wet dog”smell in my spa (1400 liters, 37 degrees Celsius)! Then on January 4 I added 100ml of Ultrashock, and then 70ml again on the 9th! No more smell! Awesome! Then on 12.1, I started adding SpaBalancer again, 60ml, and added 40ml on 13.1 (yesterday)
Problem: the chlorine value on the SpaBalancer Test strips is between 5 and 10 ppm, and more often at 10 ppm, and doesn’t go down after that! According to accounts, it should vanish! Now I’m getting hives if I use the spa!
What can I do for the high chlorine value?

You put too much UltrasShock in the water at once. I would do a partial water change, replace at least 50% of the water.
The problem you currently have: UltraShock is an oxidant. If you have too much dirt and grime in the water, a lot of UltraShock is used up in a short time. If you do not have any dirt in the water, UltraShock stays in the water for a long time because it cannot oxidize with dirt. Also, in contrast to chlorine, UltraShock is barely degraded by heat and turbulence. This is usually an advantage. In your case, however, it’s a disadvantage. The Ultrashock content will only decrease slowly.
Ultrashock should be dosed in small steps. For example, in the evening add 20 ml of UltraShock per 1000 liters of water in the spa. The next morning, measure the UltraShock content. There should be at least 0.5 to 1.0 ppm (you can measure with our test strips) UltraShock content. If it shows less, increase the dosage to e.g. 30 ml per 1000 liter of water. If more than 1.0 ppm is displayed, wait until the value falls below 1.0 ppm before adding more Ultrashock. Of course, you can also increase the UltraShock value even more if you’ve got a very dirty spa or if there’s a very unpleasant odor in the water (due to the water being contaminated). Here, I would stop at a maximum dosage to 3.0 ppm. Also, I wouldn’t enter the spa at a dosage over 5 ppm, the dose is too high.

Do you always need to use SpaBalancer with SpaBalancer UltraShock or is it enough to just use SpaBalancer on its own?-- F032

SpaBalancer on its own may be enough, however, I can't promise this with 100% certainty. In these 5 cases, we recommend the use of UltraShock.
1) If there are already deposits in the pipes, it is possible that SpaBalancer will cover them and encapsulate these deposits. This process will overload the SpaBalancer and the encapsulated deposits will later flake off and end up in the water.
2) If the whirlpool has a "cheap" unbranded filter, this will compromise the filtering.
3) If the water isn't filtered for long enough or the filter isn't sufficiently clean, the encapsulated pollutants will not be filtered out of the water. This can cause clouding and deposits on the sides of the whirlpool.
4) Because SpaBalancer also encapsulates the minerals in the water and carries them out of the water over time, in some areas where the water supplied has a high level of minerals, this can place an unusually high load on the SpaBalancer.
5) The efficacy of SpaBalancer gradually builds up. SpaBalancer will work best after 3 months.
In our experience, 80% of our customers have no problems at all when they only use SpaBalancer. But because we strive for 100% good results, we also offer Ultrashock. We recommend using UltraShock according to the dosage directions for the first few weeks or even a little more if necessary.

Is SpaBalancer itself decalcifying, or is it only SpaBalancer SoftWater which does that? -- F033

SpaBalancer removes surplus minerals from the water. However, this is a process that can take several weeks. There are minerals in the water which are in a dissolved state. SpaBalancer can't remove these dissolved minerals. These minerals are in chemical equilibrium with carbonic acid. When the water is heated and becomes turbulent, the carbonic acid escapes and the chemical equilibrium is lost. This is when limestone forms. SpaBalancer encapsulates the limestone and carries it out through the filter. Because this process of limestone formation (just before filling) can happen very fast and very strongly, it is often more than SpaBalancer can handle because the dosage is not sufficient for an enormous deposit of limestone.
There are currently three ways of preventing the formation of large limestone deposits:
1) Using SoftWater. This product does not make the water soft. It changes the ions that make up calcium and by doing so prevents the formation of limestone.
2) Ensure the pH level of the water stays below 8.0 in the first few weeks. Limestone formation takes place when the pH level is higher than 8.0. After a few weeks, the exit of the carbonic acid will have finished and the pH level will remain stable on its own.
3) Use our SoftWater Filter when filling the whirlpool. Allow at least 10 hours for the whirlpool to fill when using the filter. The water needs to run through the filter very slowly. The calcium ions are replaced with sodium ions in the filter. This makes the water softer and limestone will no longer be able to form.

For about 3 weeks now I’ve been noticing brown slime forming around the nozzles

We’ve been using SpaBalancer in our new hot tub right from the start. For about 3 weeks now I’ve been noticing brown slime forming around the nozzles. What could this be related to?

It may be encapsulated dirt. SpaBalancer encapsulates dirt at the molecular level and forms clumps around it. The clumping causes the surface area of the dirt to increase, after which it’s filtered out. However, sometimes this encapsulated dirt is deposited in areas with no filtering or only very weak filtering action. And almost no flow is present at the sides of the nozzles.

You can remove the accumulated dirt with our SpaBalancer Ultrashock product. Add 50ml of Ultrashock per 1000 liters of water. Wait two days. If the dirt is still not gone, add Ultrashock to the water again. Adding SpaBalancer Ultrashock to the hot tub in the evening will let you use your hot tub again the next day.

Smooth film in the Softub

If I don’t use my Softub for three days, a smooth film develops on the bottom. If I move my hand over it, it disappears. What is this?

SpaBalancer encapsulates foreign matter at the molecular level.
The smooth film is composed of these encapsulated foreign substances. This is because the Softub only filters when it heats up. When using SpaBalancer, 6 hours of filtration are needed per day. In summer it filters for less than an hour. For this reason, the encapsulated foreign substance sinks to the bottom and forms this film. Since you cannot lengthen the filtering time of a Softub, I would recommend the additional weekly use of SpaBalancer Ultrashock. Ultrashock oxidizes these encapsulated foreign substances and through oxidation they disappear. Between 20 and 40ml of Ultrashock per week should be sufficient. This depends heavily on the thickness of the coating in the Softub.

I have a chlorine allergy. Can I use my spa bath with SpaBalancer again?

Billions of bacteria live on our skin, which are extremely important for the functioning of our skin as the largest excretory organ of the human body. Chlorine is an oxidizing disinfectant that kills all bacteria. Therefore, with the frequent use of the spa bath, a lot of bacteria on the skin are destroyed. Sometimes, the bacteria do not recover and just die. This changes the skin. Basic functions of the skin, such as e.g. fat metabolism and the removal of contaminants through the skin pores can no longer function properly. It may cause disorders in the moisture content of the skin. It can form eczema and itchy skin. This process forms quite quickly in some people. Sometimes it can take a few years until the skin becomes sick. SpaBalancer only encapsulates harmful anaerobic bacteria such as Pseudomonas or E-Coli. All other harmless bacteria are not encapsulated and therefore do not die. The skin will therefore not be affected in its ability to function in any way. All of our customers with skin problems who have switched to SpaBalancer can now enjoy their spa bath again, free of worry.
