Dry granular chemical used in increasing hardness of the water.Dosage: 5 lb. per 10,000 gallons of water increase hardness 25 p.p.m.
Increase water hardness to prevent foaming, equipment corrosion and scaling with Calcium Hardness Up.
- Helps maintain proper calcium hardness level of 150-250 ppm
- One pound of Calcium Hardness Up will increase the calcium hardness 10 ppm in 10,000 gallons of pool water
1. Determine calcium hardness level. It should be between 150-250 ppm.
2. If the level is below 150 ppm, add Calcium Hardness Up by distributing the product over the water surface. 1 lb. of Calcium Hardness Up will increase the calcium hardness 10 ppm in 10,000 gallons of water.
