Adding Calcium To Vinyl Pool

This step mixes the water with the calcium chloride.

Adding calcium to vinyl pool.

These treatments are added to the pool s water and dissolve the deposits over a period of several weeks. Of course you don t want to operate at an acid ph either. This website is an excellent resource and it says. It is wise to wait at least 12 hours before adding any more calcium chloride to the pool.

Like any other dry chemical however calcium chloride should be pre dissolved in a bucket prior to adding to the pool. For you engineers there is some evidence calcium protects metal equipment made of steel or iron. Calcium on the low and high end of the scales will eventually cause problems and when they do be ready for some serious problems. 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.

Calcium chloride doesn t dissolve the same way as dry acid sodium bicarb or a non chlorine shock. Pool suppliers also carry calcium scaling treatments that are safe for all pool surfaces including fiberglass vinyl and steel pools. Calcium hardness is also very important to the chemical balancing of your vinyl liner swimming pool. Calcium for a liner pool can be a bit lower than a plaster pool in the range of 150 250 ppm.

As a caution do not add more than 10 lbs of calcium chloride per 10 000 gallons of pool water at one time. 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. Neither vinyl nor fiberglass has available calcium to donate to the water like a plaster pool. Following this step you need to brush the entirety of the 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. Here s why it happens.

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