Product Use and Application

Evopure Calcium Hardness is a product designed to raise the calcium hardness level in pool and spa water.

Maintaining correct calcium hardness levels in pool and spa water will ensure continued protection of pool surface finishes and equipment.

Calcium hardness levels are an integral part of the saturation index and should be checked and addressed when necessary.  All pool surfaces require calcium hardness for correct water balance, particularly when the water temperature is cooler.

The total calcium dose required, should be applied to pool and spa water in small increments of approximately one third at a time, and never added via the skimmer box.

Dosage Rates

100gm/10,000 litres will raise the calcium hardness level 10ppm.
