What is the difference between FilterClean Natural and FilterClean Classic? I use FilterClean Classic for cleaning in my inflatable whirlpool. Which cleaner is more suitable?
And: Should SpaBalancer be added again if the water becomes milky when SpaBalancer is added and there is no improvement the next day?
Answer:
The FilterClean Classic was our first filter cleaner. It cleans the filters relatively well and you can clean 10 filters with one 1.0 litre bottle. When using the FilterClean Classic, you should occasionally soak the filters in an Ultrashock solution (20 ml per 10 litres). This destroys any biofilms and bacteria and bleaches the filters. They become beautifully white again.
Unfortunately, however, the FilterClean Classic is relatively difficult to biodegrade and foams very strongly. For these two reasons we have developed the FilterClean Natural.
The FilterClean Natural has the following properties
- Dissolves dirt, grease, oil and cosmetics
- Dissolves lime deposits
- Cleans the filter fleece
- Dissolves biofilms and destroys bacteria
- Is very economical - with one can you can clean 19 filters
- Is environmentally friendly and biodegradable
- Removes unpleasant odours
- Removes brownish deposits from the filter
Since you can clean 19 filters with one can of FilterClean Natural, it is less expensive than Filter Clean Classic. I therefore recommend using the FilterClean Natural.
If after adding SpaBalancer the water becomes milky and does not improve the next day, then you should do the following:
1) Lower the pH value to 6.5.
2) Clean the filter thoroughly with FilterClean Natural.
3) Increase the filter run time. Minimum is 6 hours per day. Better increase to 12 hours or more.
4) Double the amount of Ultrashock and reduce the amount of SpaBalancer Basic by one third.
Cloudiness indicates that either limescale has formed or that there is too much dirt in the water. SpaBalancer encapsulates this dirt. It is then removed from the water via the filters. If there is too much encapsulated dirt and/or too little filter capacity, the water can become milky.
