InSpire Superior Sparkle Chemical Starter Kit can be used in your spa or hot tub. Superior Sparkle will help you to keep the water in your spa clean in a safe, simple and effective way. With only one weekly treatment, Superior Sparkle will help you to prevent calcium deposits in your system. Superior Sparkle Chemical Kit will loosen and remove the existing calcium deposits, these calcium deposits are the medium where bacteria and other micro-organisms grow. The ozone- or UV-system already in your spa, will do the rest. The Superior Sparkle Kit will destroy the bacteria and disinfect the water. The water in your spa is not only clean, but also looks crystal clear and feels nice and soft.
