Calcium hardness too low

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.

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.

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.
