It does not replace the need for regular applications of chemical sanitizers. Shock-Oxidizer restores "spent" sanitizer chloramines, so shocking your hot tub can also cut down on heavy chlorine odor. Multipurpose shock with four functions: shocks, clarifies, flocculent and pH buffer Compatible with chlorinated or brominated spas or hot tubs and those using ozone or ionization systems Restores water sparkle, removes unpleasant odors Multi-Purpose Chlorinated Shock
