Calcium Chloride

Used to increase the hardness of water, calcium chloride is highly soluble. It’s an essential part of maintaining pool health. Soft water can become corrosive as it tries to obtain calcium. This means that it damages pool surfaces and corrodes pipework and fixtures. 

When adding calcium chloride to pools, add small amounts at a time to ensure that the water does not become hard. Test as you go to ensure you don’t over-saturate. Hard water has a high level of calcium and magnesium, and this can turn the pool water cloudy, and cause a crusty, greyish scale on surfaces. This clogs filters, reduces heater efficiency, and is unsightly.
