How To Soften/Reduce Hardness In Swimming Pool Water

Accepted levels of water hardness for different pool types. The people who have swimming pools or wish to own one must take care that pools must have water with hardness levels between 200 and 400 ppm. A plaster pool is easily affected by even lower levels of water hardness so they must be filled with water with 180-220 ppm hardness.
