Low calcium hardness causes pool water to become corrosive, attacking pool surfaces, vinyl linings, metal fittings, and plastic components. Adding this product brings calcium hardness into the correct range, protecting pool infrastructure and extending the service life of surfaces and equipment. Pool service professionals and knowledgeable owners apply it during routine water balancing or when a test reveals calcium hardness below acceptable thresholds. The 4-pound package is sold as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis product is suited for use in all pool types, including concrete, fiberglass, vinyl-lined pools, and salt water systems. It is applied during regular water chemistry maintenance programs where calcium hardness testing indicates corrective treatment is needed. Residential and light-commercial pool service technicians commonly carry this product as part of a complete water balancing chemical kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRaises calcium hardness levels to protect pool surfaces from corrosive water\u003c\/li\u003e\n  \u003cli\u003eCompatible with all pool types including vinyl-lined pools and salt water systems\u003c\/li\u003e\n  \u003cli\u003eHelps prevent corrosion of metal fittings and plastic components\u003c\/li\u003e\n  \u003cli\u003e4-pound package suited for single-treatment or maintenance dosing\u003c\/li\u003e\n  \u003cli\u003eSold individually, one unit per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in all swimming pool types including concrete, fiberglass, vinyl-lined, and salt water pools as a calcium hardness adjustment treatment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis product is applied by a pool service professional or experienced owner as part of routine water balancing.
