Unlike chlorine — which both disinfects and oxidizes — MPS only oxidizes. It breaks down body oils, sweat, sunscreen, and other organic load without adding chlorine or raising chloramine smell. Owners pair it with a smaller chlorine residual (often via Ag+ Silver Ion programs or low-output salt systems) to get the comfort of a \"low chlorine\" spa without sacrificing sanitization.\u003c\/p\u003e\n\u003cp\u003eThis bottle contains\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e50 individually accessed strips\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003esealed in a moisture-resistant flip-top container — roughly a year of weekly testing for most owners, or six months if you test before every soak.\u003c\/p\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cstrong\u003ePro Tip:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThis strip does\u003cspan\u003e \u003c\/span\u003e\u003cem\u003enot\u003c\/em\u003e\u003cspan\u003e \u003c\/span\u003etest for chlorine, bromine, or hardness.
