This is a Pentair Rainbow #78DPD All-in-One kit that tests for Total and Combined Chlorine, pH, Acid Demand, and Total Alkalinity. This kit uses both drop test and DPD tablets with a color comparator. It includes a water test booklet, instructions and is housed in a red display box. The All-in-One is a perfect kit for homeowners of inground pools.
Testing sanitation levels and pH are the most important tests for pools. The chlorine level should stay between 1.0 and 3.0 parts per million (ppm) to maintain a healthy pool. A pool’s pH levels should be maintained between 7.2 and 7.6.
