How Does Calcium Levels Effect My Pool?

November 05, 2021
What is Calcium Hardness?

Calcium refers to the measure of the total hardness of which is dissolved minerals such as calcium and sodium. For most pools, the calcium hardness level should be between 200-400ppm and for spas between 150-250. Calcium can also be explained as how ‘soft’ or ‘hard’ the water is. Calcium levels are important to your pool and spa because it provides structural health of the pool itself.

How is it added?

Calcium hardness can easily be raised by added calcium chloride which will come as a flaky, granular form. You can add calcium by dissolving it in a bucket of water and broadcast into the water. When calcium chloride is added to water it will naturally heat up so make sure to keep it away from your skin. Another way to add calcium to your water is to add the required amount into your pool scoop and slowly pull through the water until there is no residue left.
