SpaBalancer UltraShock works on the basis of chlorine dioxide. It is not chlorine. It consists of one chlorine atom and two oxygen atoms.
Oxygen atoms are very strong oxidizing agents: only they react. Therefore it is a chlorine-free disinfection based on oxygen.
One chlorine atom remains and combines in the water to sodium chloride (simple table salt).
Chlorine dioxide is a water-soluble gas that is explosive with an air content of 10% or more. It can therefore not be pre-produced and transported. (At least not in a sufficiently high concentration). Therefore SpaBalancer UltraShock consists of two types of chlorine, which permanently produce chlorine dioxide in the water until the chlorine is completely used up. Due to this innovation, there is always a sufficiently large amount of chlorine dioxide in the water.
Both substances complement each other in an ideal way.
For the dosage there are water care instructions from us.
In case of problems, however, both substances can be dosed higher.
