Calcium hardness reducer swimming pool chemicals.
Refilling a portion of your swimming pool can help bring down the calcium hardness level.

It s an expensive product but i didn t feel like draining my pool and refilling it through my water softener system.

The safest and most reliable way to reduce the calcium of your pool is to remove and add fresh water back into your pool.

Unfortunately as pool owners battling disproportionate calcium hardness is one of the most difficult parts of pool maintenance because there isn t a chemical on the market that can easily be used to reduce calcium hardness though you can use a hardness increaser like calcium chloride for the opposite effect.
Be sure to wait at least 12 hours before testing the alkalinity again.
I ordered 2 bottles for my 12 000 gallon pool.
After 10 days the calcium had dropped only 20 ppm.
If you find that your calcium levels are still high you can adjust the alkalinity of the pool to control calcium hardness.
