How To Raise The Calcium Level In A Pool
Items needed to raise the calcium level in a pool:
- Calcium Chloride Flake
- Calcium Test Kit or Digital Test Kit
- Leaf Skimmer
If the calcium test indicates calcium below 400 ppm, add calcium chloride flakes, or calcium hardness increaser. Calcium chloride flakes can be found at the pool store and places that make concrete. Make sure to get the flake and not pellets.
A very general rule of thumb is that 50 lbs of calcium will raise the calcium level in a pool 20,000 gallon pool about 100 ppm. Add 50lb bags at a time and test in between each 50 lbs.
1) Add one 50lb bag at a time by putting a little at a time in a leaf skimmer and swishing it around toward the middle of the pool until it dissolves.
2) Wait a couple days before testing the water again - to make sure the calcium is thoroughly mixed into the pool water.
3) Retest the water.
Repeat process until the water is at least above 400ppm.
Tip: Calcium is very stable in the water and only drops if there is alot of rain. Test after heavy storms and about every six months.
