Hard water is water that naturally contains a lot of minerals such as limestone. Often, where you live determines the nature of the water: soft or hard. Excessively hard water can lead to limescale deposits in the pool, cloudy water and damage to the water circuits. On the other hand, water that is too soft is also problematic because it can disintegrate concrete surfaces and grout.

React quickly! If the water is too hard, replace part of the water in your pool with fresh water. To solve water that is too soft, simply add CALCIUM+ to your pool wate
