POOLIFE CALCIUM PLUS 25#

Product Description

Calcium hardness is the first chemical adjusted. Always adjust the calcium hardness before alkalinity and pH when balancing pool water. If the hardness of the pool is adjusted after alkalinity and pH, normally both will need readjusting.
Calcium hardness should be raised in small incremental changes. The hardness of the water will rise easily, but in order to lower the hardness level, part of the pool must be drained. For pools that are low in hardness, adding Poolife Calcium Plus will remedy the problem

10 pounds of Poolife Calcium Plus will raise 10,000 gallons of water 80 PPM.
