This is a Taylor Drop Test Total Chlorine (2 Oz.) Test Kit (1 drop = 1 ppm). K-9022 tests for Chlorine using drop test and Iodometric reagent.
Chlorine itself is one of the most important chemicals to monitor if you have a chlorinated pool. Ideally, you should be testing every day, especially if your pool is not covered and is exposed to rain, wind, leaves, grass clippings, and sunlight. The chlorine level should stay between 1.0 and 3.0 parts per million (ppm) to maintain a healthy pool.
