High Calcium Hardness

Attention Pool Owner, if your pool report says you have High Calcium Hardness then:

Your pool water has tested with elevated calcium hardness levels. This is a common issue throughout Texas, where local tap water already contains high natural calcium minerals.

Over time, evaporation leaves calcium behind, causing hardness levels to climb higher each season. Once calcium levels become excessive, it can lead to white scale buildup on tile, pool surfaces, heaters, and salt systems.

Unfortunately, there is no chemical that permanently reduces calcium hardness. The only effective solution is to partially drain and refill the pool with fresh water to dilute mineral concentration.

Even after a drain and refill, please note that Texas tap water is naturally hard, so calcium levels will rise again over the course of a year as you top off from evaporation. It is up to you if you wish to drain your pool down annually to maintain optimal balance and protect equipment.

DragooServices is not responsible for water quality issues, scaling, or equipment damage that may occur if the pool is not drained and refilled when calcium levels become excessive.

For best results, we recommend performing a partial drain and refill when calcium hardness exceeds 600–800 ppm, depending on your pool type and surface condition.
