Spa Boss Spa Shock is shock treatment for spas. Spa Shock is an oxidizer and can be used with chlorine and bromine disinfectant systems. It also works quickly in oxidizing many kinds of contaminants that reduce the effectiveness of your spa's chlorine or bromine. When used regularly, Spa Shock helps to reduce chlorine or bromine demand by removing those unfilterables. Spa Shock will not affect the water's pH level. Spa Shock will help restore water quality and give a boost to the chlorine or bromine levels.
