It works with both the FROG Serene Floating System (the dispenser that floats in your spa) and the factory-installed FROG In-Line System built into many hot tubs.\u003c\/p\u003e\n\u003cp\u003eThe math is straightforward. Each Serene bromine cartridge lasts 2–4 weeks; the mineral cartridge lasts up to 4 months. So one mineral cartridge plus three bromine cartridges is roughly four months of supply for a typical hot tub — perfectly aligned with the mineral cartridge's lifespan. Buying this kit costs significantly less than buying the cartridges individually, which is exactly the point.\u003c\/p\u003e\n\u003cp\u003eThe chemistry itself is the proven FROG® Serene formula: FROG® minerals plus Time Released Bromine Technology work together to sanitize your water two ways. The minerals condition the water and provide a first line of defense against bacteria, which means the bromine cartridge can run on a low, steady release — typically\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eup to 50% less bromine\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ethan a non-mineral bromine program.

Buying them together in one kit is significantly cheaper than purchasing four single cartridges over the same four months — and it means you only have to remember to reorder once per quarter instead of every 3–4 weeks.\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 aria-label=\"®\" role=\"img\"\u003eFROG®\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"FROG","offers":[{"title":"Default Title","offer_id":31751907737655,"sku":"01-14-3883","price":57.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2507\/5288\/files\/FROG_-Complete-Floating-Sanitizer-System-Kit.png?v=1708641952","url":"https:\/\/leisuretimeinc.com\/products\/frog-complete-floating-sanitizer-system-kit","provider":"Leisure Time Inc.","version":"1.0","type":"link"}
