Horizon Hardness Increaser - Calcium Chloride
Horizon Hardness Increaser is a premium-grade calcium chloride formulation specifically designed to raise calcium hardness levels in commercial swimming pools and spas. Maintaining proper calcium hardness is essential to protect pool surfaces and equipment from corrosion and etching while promoting overall water balance and clarity.
Low calcium levels can lead to aggressive water conditions that damage plaster, tile, grout, and metal components. Horizon Hardness Increaser quickly and effectively restores calcium hardness to the recommended range of 200–400 ppm, safeguarding your investment and enhancing swimmer comfort.
