One of our chemical brands, Poolife explains very well the balacing of pool water, how to understand and the importance of each chemical.
Calcium Hardness
All water contains some natural hardness, which will vary by geographic region and by source within a region. Calcium hardness (CH) refers to the dissolved calcium content of the pool water. It is wise to test the CH levels regularly to prevent problems on the pool shell or in the circulation system. Pool water with a calcium level above 1,000 ppm may become cloudy and if left long enough will form scale on pool surfaces and fittings. CH below 200 ppm can corrode pool equipment. In plaster pools it may result in pitting or etching problems.
The recommended range for calcium hardness is 200–500 ppm (up to 1,000 ppm is acceptable).
