Adding Calcium To Vinyl Pool

Like any other dry chemical however calcium chloride should be pre dissolved in a bucket prior to adding to the pool.

Adding calcium to vinyl pool.

To be safe make sure you keep the ph in your vinyl pool above 7 2. Calcium chloride gives off a lot of heat. Calcium for a liner pool can be a bit lower than a plaster pool in the range of 150 250 ppm. Following this step you need to brush the entirety of the pool.

Of course you don t want to operate at an acid ph either. Calcium on the low and high end of the scales will eventually cause problems and when they do be ready for some serious problems. Adding calcium is not as simple as it sounds you don t just throw it in 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.

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. It is wise to wait at least 12 hours before adding any more calcium chloride to the pool. As a caution do not add more than 10 lbs of calcium chloride per 10 000 gallons of pool water at one time. Neither vinyl nor fiberglass has available calcium to donate to the water like a plaster pool.

For you engineers there is some evidence calcium protects metal equipment made of steel or iron. These treatments are added to the pool s water and dissolve the deposits over a period of several weeks. This website is an excellent resource and it says. The purpose of the calcium is to protect the swimming pool plaster or marcite.

Here s why it happens. But there is little evidence that this is so for copper or brass components found in pools built in the last 15 years. Pool suppliers also carry calcium scaling treatments that are safe for all pool surfaces including fiberglass vinyl and steel 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.

There s no need to worry about a minimum calcium level in a vinyl or fiberglass pools. Calcium chloride doesn t dissolve the same way as dry acid sodium bicarb or a non chlorine shock.
