Calcite dissolves slowly and provides gradual pH correction for moderately acidic water (pH 6.0-6.9), making it ideal for applications where controlled, steady neutralization is needed without risk of over-correction. The 100% Calcite formula is particularly effective for raising pH while adding beneficial calcium minerals to the water. Sized to fit standard Slimline and Big Blue housings.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSpecifications\u003c\/b\u003e:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMade in USA\u003c\/li\u003e\n\u003cli\u003eMaterials are FDA CFR-21 and\/or NSF compliant\u003c\/li\u003e\n\u003cli\u003eDimensions: 20\" x 2.5\"\u003c\/li\u003e\n\u003cli\u003eFilter Application: pH Correction\u003c\/li\u003e\n\u003cli\u003eFilter Media: Calcite\u003c\/li\u003e\n\u003cli\u003eOperating Pressure: 20-125 psi\u003c\/li\u003e\n\u003cli\u003eTemperature Rating: 40-100°F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ResinTech","offers":[{"title":"Single","offer_id":40876461424824,"sku":"AF-20-3231","price":21.0,"currency_code":"USD","in_stock":false},{"title":"9 Pack","offer_id":40876461457592,"sku":"AF-20-3231:9PK","price":179.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2723\/8896\/files\/lamayfap2j9jlnikomsn_6c9d83f5-5fe9-4c41-afb2-5931ff6361f1.jpg?v=1792571378","url":"https:\/\/freshwitersystems.com\/products\/2-1-2-x-20-ph-neutralizing-calcite-filter-cartridge","provider":"Fresh Water Systems","version":"1.0","type":"link"}
