Turn off pump and isolate filtration system. Remove the old cartridge from the mineral vessel, insert the W28155, secure and re-start circulation. Monitor free chlorine to verify reduced demand—typically about 50% less chlorine is required when mineral system is functioning correctly.\u003c\/p\u003e\n\u003ch2\u003eMaintenance Tip\u003c\/h2\u003e\n\u003cp\u003eRegularly check the pool water every week for chlorine residual, mineral cartridge condition and general water clarity. Replace the cartridge at the six-month mark or sooner if water clarity or sanitizer levels deteriorate. Using the proper mineral cartridge helps extend the swim season with lower chemical use and improved swimmer comfort.\u003c\/p\u003e\n\u003cp\u003eSKU: W28155\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Nature2","offers":[{"title":"Default Title","offer_id":46797760725167,"sku":"W28155","price":189.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6415\/2239\/files\/nature2-m35-replacement-mineral-cartridge-w28155-chemical-feeders-8780595.jpg?v=1777066932","url":"https:\/\/freshized.com\/products\/nature2m35replacementmineralcartridgew28155zodw28155","provider":"Freshized","version":"1.0","type":"link"}
