This dry granular formula raises calcium hardness to the target range, supporting a balanced water environment.\u003c\/p\u003e\u003ch2\u003eWhy calcium hardness matters\u003c\/h2\u003e\u003cp\u003eCalcium hardness helps protect pool surfaces and components by reducing corrosion and etching when the water balance is right. Choose the appropriate target range by pool type: Vinyl pools 200-300 ppm; Tile and exposed aggregate 200-400 ppm; Marcite, fiberglass or painted pools 250-400 ppm. If tests show hardness is below the range, follow the included dosing guidance to raise levels gradually.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCalcium chloride for pools\u003c\/li\u003e\n\u003cli\u003eRapidly increases total hardness\u003c\/li\u003e\n\u003cli\u003eHelps prevent corrosion or etching of pools\u003c\/li\u003e\n\u003cli\u003eIdeal calcium hardness range 200-400 ppm\u003c\/li\u003e\n\u003cli\u003e8 ounces raises calcium hardness level 10 ppm per 5,000 gallons\u003c\/li\u003e\n\u003cli\u003ePrevents staining or etching of pool surfaces\u003c\/li\u003e\n\u003cli\u003eLow calcium hardness can cause water balance issues\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow to use\u003c\/h2\u003e\u003cp\u003eTest the water with a reliable kit to determine current calcium hardness. Mix up to 2 pounds of Pool Mate per approximately 5 gallons of pool water in a plastic bucket. Slowly pour the solution around the pool perimeter while the circulation system runs. For a 10,000 gallon pool, do not exceed 10 pounds per 2 hours.\u003c\/p\u003e\u003ch2\u003eWhat to expect\u003c\/h2\u003e\u003cp\u003eExpect a gradual adjustment toward the target range. Maintaining proper hardness can help protect surfaces, support stable chemistry, and reduce the risk of surface wear over time. Results vary with pool type, size, and existing water balance, so monitor levels and re-test as needed.\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: What is Pool Mate 32-Pounds Premium Calcium Hardness Increaser used for?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Pool Mate raises calcium hardness to target ranges, helping protect pool surfaces and equipment by maintaining balance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How should I apply Pool Mate in a typical 10,000 gallon pool?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Dissolve up to 2 lb per 5 gallons in a bucket, then slowly distribute around the pool while the pump runs; cap at 10 lb per 2 hours.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Pool Mate","offers":[{"title":"Default Title","offer_id":43992785813638,"sku":"B0CWVRCYZR","price":91.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/1602\/5478\/files\/pool-mate-calcium-chloride-powder.jpg?v=1779050501","url":"https:\/\/patiozora.com\/products\/pool-mate-32-pounds-premium-calcium-hardness-increaser-for-pools-100-calcium-chloride","provider":"PatioZora","version":"1.0","type":"link"}
