Calcium Hardness In Vinyl Liner Pool

Calcium on the low and high end of the scales will eventually cause problems and when they do be ready for some serious problems.

Calcium hardness in vinyl liner pool.

A hardness of 10 is fine in a plastic pool. High calcium is rarely a problem if other lsi factors are adjusted properly 500ppm calcium hardness is easily managed without scale formation. If a vinyl liner s calcium level is too low this soft water situation could lead to foaming and other water problems and can harm the vinyl. If your pool has a vinyl or fiberglass liner the calcium hardness level should be between 175 parts per million ppm and 225 ppm.

In general the whole saturation index thing the pool industry has wasted so much paper on doesn t apply to most pools. Calcium hardness is also very important to the chemical balancing of your vinyl liner swimming pool. For vinyl pools calcium should be between 150 250 ppm. Calcium for a liner pool can be a bit lower than a plaster pool in the range of 150 250 ppm.

Hardness at any level is only an issue in a plastic pool pvc pipes vinyl liner polymer pump if it s high. If you have a concrete or plaster pool keep the level between 200 ppm and 275 ppm. If calcium hardness goes above 400 ppm you will likely see a white flaky crust on the liner and pool equipment. It also produces itchy skin.

Truth be known vinyl liner and fiberglass pools are likely to decline faster in a low calcium environment.
