Pool Care Calcium Balance Treatment 10lbs

Pool Care Calcium Balance Treatment returns water to its normal hardness level. It also prevents corrosion, etching and pitting of exposed concrete surfaces. Usage: Calcium Balance Treatment should be added by scattering it over the surface of the pool water so it will dissolve more rapidly. A dose of 1 ¼ lbs of Calcium Balance Treat per 10,000 gallons of water will raise calcium hardness approximately 10 ppm.
