What is calcium hardness?

12/16/2018

Calcium Hardness (or Total Hardness) refers to the amount of calcium and other minerals that make the water hard. Swimming pools require a hardness level of 150 to 400 ppm. Less than 150 and the water will be corrosive, more than 400 and the water will be scale forming.
