This is a Taylor Drop Test Hardness Calcium/Total EDTA Titration Test Kit. The K-1722 Kit tests for hardness, calcium and total using the drop test system and EDTA titration method. The EDTA includes inhibitors to revent metal interference.
Calcium hardness is a necessary component in pool water because it helps prevent leaching out of certain substances in pool equipment. It works in conjunction with alkalinity and pH. You would balance alkalinity, pH, then calcium hardness in your pool, in that order. That is because adjusting alkalinity often affects pH. Adjusting both alkalinity and pH often affects your calcium hardness.
