Those silver ions inhibit bacterial growth continuously, meaning you can run your spa on a much lower chlorine residual than a chlorine-only spa would require.\u003c\/p\u003e\n\u003cp\u003eThis is one of the most popular FreshWater products because it solves a real comfort problem: high chlorine smell. Owners running a chlorine-only system often complain about strong sanitizer smell, dry skin, irritated eyes, and faded swimsuits — all caused by maintaining enough chlorine to handle bacteria\u003cspan\u003e \u003c\/span\u003e\u003cem\u003eand\u003c\/em\u003e\u003cspan\u003e \u003c\/span\u003eoxidize organic contaminants single-handedly. Add an Ag+ cartridge, and the silver ions handle most of the bacterial inhibition.

Silver ions inhibit bacteria but do not oxidize body oils, sunscreen, sweat, or other organic load brought in by bathers. You still need to add a small amount of dichlor or MPS (non-chlorine shock) regularly to oxidize organics and keep water clear. Owners who skip this step end up with cloudy water and assume the cartridge is defective — it isn't. The two-part approach is how the system is designed to work.\u003c\/p\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cstrong\u003ePro Tip:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThink of Ag+ like the long-haul shift of your sanitizer team — it handles the steady, continuous bacterial inhibition. The chlorine or MPS you add periodically is the cleanup crew — it handles the contamination bathers bring in. You need both, but with Ag+ in the filter, you need much less of the chlorine.\u003c\/div\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cstrong\u003e\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cp\u003e\u003cspan role=\"img\" aria-label=\"®\"\u003eFreshWater®\u003c\/span\u003e\u003cspan role=\"img\" aria-label=\"®\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"FreshWater","offers":[{"title":"Default Title","offer_id":4575778177061,"sku":"80010","price":34.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2507\/5288\/files\/FreshWater_Ag_Silver_Ion_Sanitizer.jpg?v=1778192806","url":"https:\/\/leisuretimeinc.com\/products\/freshwater-ag-silver-ion-sanitizer","provider":"Leisure Time Inc.","version":"1.0","type":"link"}
