Supplied here as a convenient 2 × 2 liter pack, it’s intended to be added via the skimmer so the product forms a thin, active coating on sand, cartridge or DE filter media.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Phosfree actually lower phosphates in my pool?\u003c\/h3\u003e\n\u003cp\u003eWhen introduced into the skimmer, Phosfree distributes through the circulation system and deposits a microscopic lanthanum coating on the filter media. Phosphate molecules bind to this coating in the filter, becoming trapped and removed from the water as filtration continues.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eLanthanum compounds adsorb phosphates directly from flowing water.\u003c\/li\u003e\n  \u003cli\u003eFilter-based action avoids clouding by keeping reactions inside the filter.\u003c\/li\u003e\n  \u003cli\u003eContinuous filtration gradually drives phosphate levels down to very low values.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhen and how should I apply the Phosfree 2L bottles?\u003c\/h3\u003e\n\u003cp\u003eApply Phosfree via the skimmer following product dosing instructions for your pool volume and existing phosphate level. It’s typically used after testing phosphates and then added during normal circulation so the filter picks up and retains the lanthanum coating.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTest phosphate levels before treatment to determine required dose.\u003c\/li\u003e\n  \u003cli\u003eAdd through the skimmer while the pump and filter are running.\u003c\/li\u003e\n  \u003cli\u003eRepeat dosing as needed based on subsequent phosphate tests and water turnover.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill Phosfree cloud my water or disrupt filtration?\u003c\/h3\u003e\n\u003cp\u003ePhosfree is formulated to work in the filter rather than in the pool water, which minimizes cloudiness. Because the active chemistry bonds in the filter, it reduces the chance of visible clouding while maintaining normal filter operation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned to coat filter media, not stay suspended in the pool.\u003c\/li\u003e\n  \u003cli\u003eCompatible with common filter types: sand, cartridge, and DE.\u003c\/li\u003e\n  \u003cli\u003eRegular backwashing or cleaning removes accumulated phosphate-laden media when necessary.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does using Phosfree change routine pool maintenance?\u003c\/h3\u003e\n\u003cp\u003eUsing Phosfree can simplify maintenance by reducing phosphate levels — a common nutrient for algae — which in turn helps sanitizer work more effectively. It complements, rather than replaces, normal testing, sanitizing and filtration practices.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFewer phosphate-driven algae issues when levels are kept low.\u003c\/li\u003e\n  \u003cli\u003eMaintains clearer water so visual checks are easier and more reliable.\u003c\/li\u003e\n  \u003cli\u003eContinue routine sanitizer, pH and filter maintenance schedules.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Natural Chemistry Phosfree in the 2 × 2 liter pack is suited to pool owners and service professionals who test regularly and want a proactive, filter-based solution to manage phosphate levels. It’s recommended for pools with recurring phosphate buildup or algae concerns, and for anyone seeking a product that integrates into existing circulation and filtration systems rather than requiring large-scale chemical shocks. Always follow label directions and test phosphate levels to determine appropriate dosing before use.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How often should I dose Phosfree?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Dose based on phosphate test results and pool volume; reapply when tests show phosphate rebound or per product directions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is Phosfree safe for all filter types?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—Phosfree is formulated for sand, cartridge and DE filters and works by coating the filter media.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Natural Chemistry","offers":[{"title":"Default Title","offer_id":54204940353720,"sku":"B00S8GTL3A","price":146.38,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/0636\/7416\/files\/natural-chemistry-phosfree-bottle-front.jpg?v=1790637332","url":"https:\/\/canadianlawn.ca\/products\/natural-chemistry-phosfree-phosphate-remover-2-x-2l-pack-lanthanum-filter-coating-to-reduce-phosphates-prevent-algae","provider":"Canadian Lawn","version":"1.0","type":"link"}
