7 in 1 Test Strips

7-in-1 test strips make pool water testing fast and simple — no reagents, no comparators, no guesswork. With a single dip, they measure key water parameters like free chlorine,  total chlorine, bromine, pH, total alkalinity, hardness, and stabilizer (CYA), helping owners stay on top of water balance and spot issues early. A must-have quick-check tool for every pool season.
