Do Vinyl Pools Need Calcium

But there is little evidence that this is so for copper or brass components found in pools built in the last 15 years.

Do vinyl pools need calcium.

Plain old water believe it or not is very aggressive. Of course you don t want to operate at an acid ph either. Yes calcium is still important to all types of pools. 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.

Generally i don t have my customers deal with the calcium until the pool is sanitized and clear. Your pool can only hold so much calcium in your pool dissolved as a calcium salt before it reaches its saturation point. Here s why it happens. It s ok to wait a week or so on the calcium while you fix the other issues.

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. A low level can result in foaming which is unpleasant but shouldn t harm the liner. Any additional calcium forms in the water as calcium carbonate and is visible and suspended in the water. Our proven treatment process is very effective in removing and preventing calcium deposits from plaster quartz vinyl lined and fiberglass pools.

To be safe make sure you keep the ph in your vinyl pool above 7 2. However it s not as big or pressing of an issue as chlorine ph and all the other stuff. For you engineers there is some evidence calcium protects metal equipment made of steel or iron. For vinyl pools calcium should be between 150 250 ppm.

Neither vinyl nor fiberglass has available calcium to donate to the water like a plaster pool.
