We have increased the addition of ultrasound and are at about three times the recommended dose. The water is clear, but has a very musty smell. Despite the high amount of ultrasonic shock, the measuring strip still shows a value of 0. According to this, Ultraschock would be underdosed, but I am concerned about overdosing, which would otherwise endanger foil. How should I proceed?
Answer:
the Ultrashock is a strong base (pH above 12). In undiluted form it bleaches the foil. When you add it to the water, the base is neutralized (pH value 7.0). It is then completely harmless for the foil. In contrast to chlorine-containing or bromine-containing agents. These agents contain and form acids in the water and can thus extract plasticizers from the foils and plastics and thus damage them. The plastics fade and become brittle. This cannot happen to you with our products.
A musty smell indicates deposits in the pipes. Also the fact that the Ultrashock drops very quickly back to 0. This happens because the Ultrashock oxidizes and removes the deposits. If there are a lot of deposits, the Ultrashock quickly disappears. Unfortunately I can only give you the tip to leave the Ultrashock content permanently between 0.5 and 2.0 mg/l. As soon as all deposits are oxidized, the Ultrashock content will stabilize over several days and will not decrease further. When you're not going swimming. After a bath, the Ultrashock content decreases because organic dirt has been introduced into the water. During the time you permanently have Ultrashock in the water, you can reduce the addition of SpaBalancer by 75%.
I cannot recommend intensive basic cleaning for a foil pool. But you could try cleaning with SystemFlush. It can remove many deposits that you don't have to oxidize with Ultrashock.
