Application:
To Increase Calcium Hardness by 100 ppm:
-Add 1.2 pounds per 1,000 gallons
-Add 12.0 pounds per 10,000 gallons
-Add 60.0 pounds per 50,000 gallons
*Low calcium hardness can cause corrosion to
metal equipment and plaster walls
*High calcium hardness can cause water to become
cloudy and also leave scale or stain on the walls of the pool
*It is recommended to keep calcium hardness between
250-300ppm
The only way to lower Calcium Hardness is to
drain water out of the pool and add fresh water.
