Pool Chemistry Definitions: Total Hardness


Pool water chemistry is the most misunderstood, yet vital component to overall pool care. Not only does proper water chemistry protect the swimmers using the pool, but it also protects the swimming pool itself.

Gas heaters, electrical heat-pumps, filters, and even the vinyl-liner can all suffer severe damage from unbalanced pool water. In order to clear up some of the confusion surrounding this subject, we have listed some of the more important water chemistry terms below.

Total Hardness

Total Hardness refers to the amount of calcium and magnesium in your pool water. When total hardness is too high, scale can form causing the water to appear cloudy. When total hardness is too low, the water will corrode metal fixtures including copper components found in gas heaters and electrical heat-pumps. The total hardness should measure 150 – 300 ppm.
