We have had an outdoor whirlpool since November 2020. Up to now we have used chlorine for disinfection. We have been using your products SpaBalancer Basic and UltraShock for about two weeks. The question now arises as to whether I still need to add chlorine when using UltraShock? Can this be omitted or reduced?
Answer:
If you use the SpaBalancer water care system, you do not need any additional chlorine. It is a fully-fledged system that does not need to be supported by further disinfection or oxidation agents. If you want to use additional chlorine for cost reasons, then that is possible. The SpaBalancer products can be used in combination with chlorine. However, you must ensure that you only use chlorine products without cyanuric acid. In other words, no organic chlorine. Cyanuric acid accumulates in the water and also impairs the effectiveness of the UltraShock.
However, you can use so-called inorganic chlorine (available from us as "Anorganic Shock"). It is also called Calcium Hypochlorite Granulate. However, this chlorine increases the water hardness. Therefore, it is not recommended for hard water.
