SpaPure Multi Shock Extra | Chlorine Spa Shock

SpaPure Multi Shock Extra is a powerful, chlorine-based multi-function shock for hot tubs and spas. Built on dichlor (sodium dichloro-s-triazinetrione), it does several jobs in one fast-dissolving granular product: it kills algae, oxidizes organic waste, restores water clarity, and provides long-lasting chlorine protection — and it can even serve as a primary chlorine sanitizer on its own.

Every soak leaves behind sweat, oils, lotions, and other organic waste that clouds water, feeds algae, and consumes your sanitizer. A chlorine shock blasts through that load with a strong dose of free available chlorine — sanitizing, oxidizing, and clearing the water in a single step. Because it's chlorine-based, it both kills and oxidizes, where a non-chlorine oxidizer only cleans up waste without sanitizing.

It works fast, too: once the chlorine settles into the safe range, the spa can be used in as little as 15 minutes. The result is cleaner, clearer, better-balanced water with a fresh feel.
