Pool Calcium Hardness

.
Pool Calcium Hardness, or total hardness as it is sometimes called, is the measurement of dissolved calcium and other minerals in your pool water. Like pH and alkalinity, you must keep calcium hardness within a certain range or you will develop problems. If your calcium hardness is too high, then you will develop scale buildup and cloudy water, while if too low can cause corrosion to pool plumbing, surfaces, and other equipment. We offer a wide range of treatments and testing supplies to keep your calcium hardness in the optimal range, providing the most comfortable and best looking pool environment possible.
