Pool Math Calculator vs 2NT*

Test the water. Get a plan. Pool Calculator turns your test strip or drop-kit readings into clear steps: what to add, how much, in what order, and when it's safe to swim again. • A plan after every test, with how long to wait between steps • Doses in fl oz, cups, jugs and pounds, sized for your pool and the products you buy: liquid chlorine, bleach, cal-hypo, muriatic acid, soda ash, borax and more • A lifeguard flag on your pool: green, yellow or red, and a tap tells you why • Green or cloudy water? Shock doses sized for your stabilizer, and a clear sign when the algae is really gone • It remembers what you've added, so nothing gets dosed twice • Your pool in 3D: rectangle, round, oval or kidney; plaster, vinyl or fiberglass; chlorine or salt water • What if: see what an addition will do before it goes in • Water balance (CSI) to protect plaster and equipment • History with trend charts, test reminders and CSV export for your pool service • Several pools, your own targets, U.S. or metric units Chlorine targets follow your stabilizer (CYA) level, the way pool experts recommend. Your pool data stays on your device. Doses are estimates for planning: always follow the product label, add one chemical at a time, and retest before adding more.
