Pool water hardness products

Water hardness, measured by calcium levels, protects your equipment and stabilizes the water balance. Too low a hardness level promotes corrosion, while too high a hardness level leads to limescale deposits and cloudy water. Maintaining the correct level ensures clear water and a long-lasting pool. To learn more about complete pool water balancing, see our guide.

Use a calcium hardness increasing product. Dissolve it in a bucket of warm water (be careful: the solution will get hot), then slowly pour it into the pool with the pump running. The ideal area for a pool is generally between200 and 300 ppm.

To reduce water hardness, there is no common chemical product: you must dilute the pool water by partially draining it and adding fresh water. Excessive hardness can lead to white deposits, cloudy water, and damage to equipment.

Fill a large bucket with lukewarm water, gradually add the water hardness increaser, stir, and allow it to dissolve completely. Caution: the reaction may release heat. Then pour the solution around the pool with the pump running.
