(Diatomaceous Earth) filter grid engineered to restore peak filtration performance in your pool. Standing 18\" tall and covering 36 square feet of filtration area, this single full grid captures microscopic particles, dirt, and debris down to 2–5 microns — delivering crystal-clear water all season long. Built with heavy-duty, chemically resistant materials and sonically welded stitching, the APCFGR2 is a direct drop-in replacement for Hayward, Pentair, Waterway, Jacuzzi, Sta-Rite, and other popular 36 sq ft D.E. filter systems.\u003c\/p\u003e\n\u003ch3\u003e🚩 PRO TIP\u003c\/h3\u003e\n\u003cp\u003eWhen replacing individual D.E. grids, always inspect the manifold and standpipe for cracks before installation. After replacing, backwash the filter first to seat the new grid, then re-charge with fresh D.E. powder at the rate of 1 lb per 10 sq ft of filter area (approximately 3.6 lbs for a 36 sq ft filter). For a complete 36 sq ft overhaul, pair with the APCFS2003 Complete Set (7 full grids + 1 partial grid).\u003c\/p\u003e\n\u003ch3\u003ePRODUCT FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ \u003cstrong\u003e36 Sq Ft Filtration Area:\u003c\/strong\u003e Captures particles down to 2–5 microns for crystal-clear pool water.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eUniversal Compatibility:\u003c\/strong\u003e Direct replacement for Hayward DEX3600DA, Pentair FNS Plus 36, Waterway Crystal Water, Jacuzzi Earthworks EW 36, Sta-Rite, and other 18\" D.E. filter systems.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eHeavy-Duty Construction:\u003c\/strong\u003e Chemical-resistant, mildew-resistant, and rot-resistant materials built for long-term pool use.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eSonically Welded Stitching:\u003c\/strong\u003e Reinforced seams prevent bypass and ensure every drop of water passes through the filtration media.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eReinforced Core:\u003c\/strong\u003e Added internal stability prevents grid collapse under high flow rates.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003ePrecise 18\" Fit:\u003c\/strong\u003e Engineered to the exact height specification for a snug, leak-free fit in compatible filter housings.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eRestores Filter Efficiency:\u003c\/strong\u003e Worn or torn grids reduce filtration — a fresh grid brings your D.E. filter back to like-new performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e⚙️ TECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e APCFGR2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiltration Area:\u003c\/strong\u003e 36 sq ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrid Height:\u003c\/strong\u003e 18\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrid Width:\u003c\/strong\u003e 11\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.6 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 842524104211\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Reference Part Numbers:\u003c\/strong\u003e Unicel FG-1003, Filbur FC-9330, Hayward DEX3600DA, Hayward Micro-Clear DEX3600DA, Pentair FNS Plus 36, Waterway Crystal Water 818-3940, Jacuzzi Earthworks EW 36 42-2970-03-R, Sta-Rite WC208-75\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWHY SHOP WITH AL'S COOL POOL STORE?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ Fast, reliable shipping on every order\u003c\/li\u003e\n\u003cli\u003e✅ Genuine OEM and top-brand parts only\u003c\/li\u003e\n\u003cli\u003e✅ Knowledgeable pool \u0026amp; spa experts ready to help\u003c\/li\u003e\n\u003cli\u003e✅ Hassle-free returns and satisfaction guarantee\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APC","offers":[{"title":"Default Title","offer_id":44111503884423,"sku":"APCFGR2","price":36.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0634\/1217\/4983\/files\/apc-apcfgr2-de-filter-grid-36-sq-ft-18-inch-front-view.jpg?v=1774289398","url":"https:\/\/alscoolpoolstore.com\/products\/apc-de-full-grid-apcfgr2-18-36-sq-ft","provider":"Al's Cool Pool Store","version":"1.0","type":"link"}
