Calcium / Hardness Test Kit ZeroChlor Pool Systems require a specific calcium/hardness level of 250-400ppm in order to properly sanitize the pool water. Once the calcium/hardness level has been attained it will generally only need to be adjusted once or twice per year. 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!
