KEEPS WATER IN BALANCE
Description
KEEPS WATER IN BALANCE
Calcium Builder is used to increase calcium hardness in pools and spas. Water containing less than 200 ppm of calcium is considered “soft” or “aggressive” water. Soft water is not recommended because it etches and slowly erodes plaster, grout, concrete and heat exchangers. Calcium hardness should be kept between 200-400 ppm.
