Adding Calcium To Vinyl Pool

Adding calcium is not as simple as it sounds you don t just throw it in the pool.

Adding calcium to vinyl pool.

Calcium chloride gives off a lot of heat. To be safe make sure you keep the ph in your vinyl pool above 7 2. Low calcium levels in the 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.

Of course you don t want to operate at an acid ph either. But there is little evidence that this is so for copper or brass components found in pools built in the last 15 years. This website is an excellent resource and it says. Calcium hardness is also very important to the chemical balancing of your vinyl liner swimming pool.

It is wise to wait at least 12 hours before adding any more calcium chloride to the pool. There s no need to worry about a minimum calcium level in a vinyl or fiberglass pools. Neither vinyl nor fiberglass has available calcium to donate to the water like a plaster pool. This step mixes the water with the calcium chloride.

Here s why it happens. Like any other dry chemical however calcium chloride should be pre dissolved in a bucket prior to adding to the pool. Calcium for a liner pool can be a bit lower than a plaster pool in the range of 150 250 ppm. 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.

For you engineers there is some evidence calcium protects metal equipment made of steel or iron. Calcium chloride doesn t dissolve the same way as dry acid sodium bicarb or a non chlorine shock. The purpose of the calcium is to protect the swimming pool plaster or marcite. Pool suppliers also carry calcium scaling treatments that are safe for all pool surfaces including fiberglass vinyl and steel pools.

Calcium on the low and high end of the scales will eventually cause problems and when they do be ready for some serious problems. Following this step you need to brush the entirety of the pool.
