Calcium hardness in vinyl 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. Hardness at any level is only an issue in a plastic pool pvc pipes vinyl liner polymer pump if it s high. Here s why it happens. Low calcium levels in the pool.

If your pool has a vinyl or fiberglass liner the calcium hardness level should be between 175 parts per million ppm and 225 ppm. Low calcium as is often the case will cause long term serious damage especially to plaster vinyl liners grout in between tiles metal rails and even concrete decking around the pool. For vinyl pools calcium should be between 150 250 ppm. If calcium hardness goes above 400 ppm you will likely see a white flaky crust on the liner and pool equipment.

In general the whole saturation index thing the pool industry has wasted so much paper on doesn t apply to most pools. The ideal reading for calcium hardness in pool water is about 200 to 400 parts per million. 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. It also produces itchy skin.

A low level can result in foaming which is unpleasant but shouldn t harm the liner. If you have a concrete or plaster pool keep the level between 200 ppm and 275 ppm. Calcium for a liner pool can be a bit lower than a plaster pool in the range of 150 250 ppm.
