SpaPure Oxidizing Shock is an oxygen-based, non-chlorine spa shock built around potassium monopersulfate (MPS). Every time someone soaks, they leave behind sweat, body oils, lotions, cosmetics, and dead skin — a layer of organic bather waste that has nothing to do with bacteria but everything to do with cloudy, dull, tired-looking water. That waste is also what quietly drains your sanitizer. Left alone, your chlorine or bromine spends itself burning off oils and organics instead of doing its real job — controlling bacteria. Shocking with an oxidizer clears that organic load so your sanitizer stays free to protect the water, and so it stops getting used up before its time. Because SpaPure Oxidizing Shock is oxygen-based rather than chlorine-based, it does the cleanup without the side effects: it won't raise your chlorine, calcium hardness, or cyanuric acid, and it won't bleach or fade your shell, pillows, or cover. And it works fast — the water is ready to use again about 15 minutes after you apply it. Pro Tip: Shock is not sanitizer. SpaPure Oxidizing Shock is an oxidizer — it cleans up organic waste, but it does not sanitize on its own. Keep running your regular chlorine or bromine for sanitizing, and use this weekly to keep that sanitizer working at full strength. The two work as a team. Brand SpaPure®
