AquaChek 511242A 4 Way Chlorine Test Strips 50 Count 12 per Case
AquaChek 511242A Chlorine 4-in-1 strips provide a convenient way to check four key water-balance readings: free chlorine, pH, total alkalinity, and stabilizer. The 50-count bottle is suitable for routine chlorine-pool or spa testing.
Use the bottle’s color chart and the labeled reading time to interpret each test. Regular readings help you decide when water needs adjustment; keep the cap closed and the strips dry between uses.
