Calcium/Hardness Test Kit

Calcium / Hardness Test Kit

    ZeroChlor Pool Systems require a specific calcium/hardness level of 250-400ppm. these levels are required to provide the proper level of electrolysis in the titanium stack, which sanitizes the pool water.  Once the calcium/hardness level has been attained it will generally only need to be adjusted twice per year. Testing monthly is recommended. This swimming pool water test kit is a simple and effective way to keep track of your calcium/hardness levels in your swimming pool water. 

    For instructions on how to use this test kit please see our instructional video in the Education Center.  Thanks!
