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. Pro Tip: Chlorine shock vs. non-chlorine shock — know which you're reaching for. Multi Shock Extra is chlorine-based, so it both sanitizes and oxidizes, and it raises your chlorine level. If you'd rather clear bather waste without adding chlorine (or without waiting for chlorine to drop before soaking), reach for the non-chlorine Oxidizing Shock instead. Many owners keep both and choose based on the situation. Brand SpaPure®
