Available in a 16 oz container, this white flake formula dissolves readily in water without clouding the spa. Low calcium hardness causes water to become aggressive and corrosive, attacking equipment surfaces, fittings, and shell materials over time. Adding this increaser brings hardness levels up safely and helps protect spa components. Pool and spa service technicians rely on this type of balancer as a standard part of a complete water chemistry program.\u003c\/p\u003e\u003cp\u003eThis product is used in residential and light-commercial spas and hot tubs where calcium hardness levels have tested below the recommended range. Proper hardness balance reduces corrosion on heater elements, pumps, and plumbing components. It is applied directly to spa water as part of a routine chemical balancing process. The flake form allows for controlled dosing during water startup or ongoing maintenance cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReadily soluble flake form dissolves without clouding water\u003c\/li\u003e\n\u003cli\u003eRaises calcium hardness levels to help prevent corrosive water conditions\u003c\/li\u003e\n\u003cli\u003eOdorless white flakes for clean handling during dosing\u003c\/li\u003e\n\u003cli\u003e16 oz container suitable for single-treatment or maintenance use\u003c\/li\u003e\n\u003cli\u003eFormulated as a water balancer for spa and hot tub applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard calcium hardness balancer for residential and light-commercial spas and hot tubs requiring hardness level adjustment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis chemical is applied by pool and spa service technicians or knowledgeable operators.
