Calcium Hardness Vinyl Pool

Fortunately calcium hardness changes rather slowly so a once a month testing and adjustment should be all you need.

Calcium hardness vinyl pool.

Calcium for a liner pool can be a bit lower than a plaster pool in the range of 150 250 ppm. For vinyl pools calcium should be between 150 250 ppm. A low level can result in foaming which is unpleasant but shouldn t harm the liner. But what it depends on isn t that difficult.

If calcium hardness goes above 400 ppm you will likely see a white flaky crust on the liner and pool equipment. 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. The ideal reading for calcium hardness in pool water is about 200 to 400 parts per million.
