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.
