- Its example dose exposes the arithmetic: 3 ppm × 15,000 gallons ÷ 781.8 = 57.6 fluid ounces.
Field notes
The example calculation converts 3 ppm in a 15,000-gallon pool to 57.6 fluid ounces, then expresses that as roughly seven cups of 10% liquid chlorine. The page says dose targets use stabilizer (CYA) levels and that users can inspect the math; it also describes a history of tests, treatments, notes, and settings, plus CSV export on every plan. Forecast warnings are identified as a Premium feature.
