GLB Calcium Hardness Up, 25Lb | 71214
The GLB Calcium Hardness Up is a 25-pound granular product designed to increase the calcium hardness levels in swimming pool water. Maintaining appropriate calcium hardness is essential to prevent equipment corrosion, scaling, and foaming, thereby ensuring the longevity and efficiency of your pool system.
Key Features:
-
Prevents Equipment Corrosion: By elevating calcium levels, it safeguards metal components and pool surfaces from corrosive damage.
-
Reduces Scaling and Foaming: Helps maintain water balance, minimizing the risk of scale formation and foam development.
-
Compatible with Various Sanitizers: Safe for use with chlorine, bromine, ozone, saltwater pools, and biguanide sanitizing systems.
Application Instructions:
-
Test Water Hardness: Determine the current calcium hardness level using a reliable test kit. The ideal range is between 150-250 parts per million (ppm).
-
Calculate Dosage: If the calcium hardness is below 150 ppm, add GLB Calcium Hardness Up to raise the level. As a guideline, 1 pound of the product will increase the calcium hardness by 10 ppm in 10,000 gallons of water.
-
Add to Pool: Evenly distribute the calculated amount of product over the water surface.
-
Circulate Water: Run the pool’s filtration system to ensure thorough mixing and distribution.
Regular monitoring and adjustment of calcium hardness levels are recommended to maintain optimal water quality and protect pool infrastructure.
