Water testing & smart monitors

In desert heat, chemistry changes fast. Test at least weekly, and two or three times a week in summer.

Three ways to test

  • Test strips: fast and easy for routine checks.
  • Drop-based kits (FAS-DPD): more accurate for chlorine, calcium and stabilizer.
  • Smart monitors: floating sensors send pH and chlorine readings to your phone. Great for trends; confirm with a kit now and then.

What to test

Free chlorine, pH, alkalinity, calcium hardness and stabilizer (CYA), plus salt for saltwater pools. See the ranges on our home page.
