Does Calcium Hardness Matter Vinyl Pool

I thought i d bring that discussion over here as well.

Does calcium hardness matter vinyl pool.

Water is crystal clear. I ve read on the forums that calcium hardness unless it is too high is not really an issue for vinyl lined pools. If you have a concrete or plaster pool keep the level between 200 ppm and 275 ppm. 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. 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. Here s your favorite answer. Calcium hardness is also very important to the chemical balancing of your vinyl liner swimming pool.

Here s why it happens. So as you can see the calcium harness is below the recommended range of 200 400 or even below the 130 number i saw floating around here a while ago. Calcium hardness ch for vinyl pool liners there is this discussion over at trouble free pool that has uncovered the apparent fact that granulated calcium carbonate is the common filler in vinyl pool liners. Low calcium levels in the 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. 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.
