How a water test works

Testing your water sounds technical, but it's really just five small steps. Here's the whole thing, start to finish.

  1. 1

    Grab a sample

    Scoop water from elbow-deep, away from the returns and skimmer, where the water is most representative.

  2. 2

    Dip the test

    Dip a test strip (or add the reagent drops) and give it a moment. The pads change color based on what is in your water.

  3. 3

    Read the colors

    Each pad turns a shade that maps to a number — chlorine, pH, alkalinity, and more. Match them against the chart.

  4. 4

    Enter your numbers

    Type the readings into the app (or snap a photo of the strip). No charts to memorize, no math in your head.

  5. 5

    Get your plan

    The chemistry engine reads everything together and tells you exactly what — if anything — to add, and when to retest.

That's it. Testing once or twice a week takes a couple of minutes and is the single habit that keeps a pool easy. Got readings in front of you? Run them through the free calculator — it's the same server-side chemistry engine the app uses, and it tells you the product and the amount for your pool's gallons. Free, no account, no limit. The app adds the part a calculator can't: it remembers your numbers, so you see trends instead of just today's snapshot.
