Do Vinyl Pools Need Calcium

Our treatments remove almost any calcium buildup in pool surfaces.

Do vinyl pools need calcium.

It s ok to wait a week or so on the calcium while you fix the other issues. Your pool can only hold so much calcium in your pool dissolved as a calcium salt before it reaches its saturation point. To be safe make sure you keep the ph in your vinyl pool above 7 2. You do not have to drain your pool to remove calcium deposits.

For you engineers there is some evidence calcium protects metal equipment made of steel or iron. Neither vinyl nor fiberglass has available calcium to donate to the water like a plaster pool. 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. That is to say in calcium deficient water a plaster surface gives up necessary surface calcium to attain equilibrium with the water causing premature surface failure.

But there is little evidence that this is so for copper or brass components found in pools built in the last 15 years. Generally i don t have my customers deal with the calcium until the pool is sanitized and clear. Plain old water believe it or not is very aggressive. Any additional calcium forms in the water as calcium carbonate and is visible and suspended in the water.

A low level can result in foaming which is unpleasant but shouldn t harm the liner. Yes calcium is still important to all types of pools. Of course you don t want to operate at an acid ph either. Here s why it happens.

If calcium hardness goes above 400 ppm you will likely see a white.
