Calcium Hardness Vinyl Pool

But what it depends on isn t that difficult.

Calcium hardness vinyl pool.

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 you have a concrete or plaster pool keep the level between 200 ppm and 275 ppm. The ideal reading for calcium hardness in pool water is about 200 to 400 parts per million. If calcium hardness goes above 400 ppm you will likely see a white flaky crust on the liner and pool equipment.

Fortunately calcium hardness changes rather slowly so a once a month testing and adjustment should be all you need. 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. If your pool has a vinyl or fiberglass liner the calcium hardness level should be between 175 parts per million ppm and 225 ppm.
