They snap into the reusable Spa Frog floating holder.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow the system works\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eMinerals do part of the sanitizing work, which means the bromine cartridge has less to do. King Technology rates the result at up to 50 percent less bromine than running a standard bromine spa. Both cartridges are adjustable, so a small two person spa and a large one can run the same system at different settings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReplacement schedule\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe two cartridges are on different clocks. The mineral cartridge goes about 4 months, so it lines up naturally with draining and refilling the spa. The bromine cartridge runs 2 to 4 weeks depending on how heavily the spa is used, which is why the kit is weighted three bromine to one mineral.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAny spa\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe floating holder is reusable and is not tied to a particular spa brand or a built in system, so this is a straightforward way to sanitize a spa that has no dedicated frog housing.\u003c\/p\u003e","brand":"King Technology","offers":[{"title":"Default Title","offer_id":48627857457364,"sku":"KTC-45-568","price":64.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_b2faf4c7-c292-4b20-876f-e1c83c3efe65.jpg?v=1788728513","url":"https:\/\/www.activepoolsupply.com\/products\/spa-frog-cartridge-refill-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
