PoolLevels: pool chemistry without the guesswork
A privacy-first pool-water calculator that uses test readings to estimate saturation index and recommend one measured chemical addition.
Field notes
PoolLevels models pool chemistry from pH, alkalinity, calcium hardness, cyanuric acid, temperature, pool volume, and related context, then presents a single dose with checkable arithmetic. Its worked 20,000-gallon example produces a +0.54 saturation index and a 52-fluid-ounce muriatic-acid recommendation. The page also documents an important limitation: dissolved solids are assumed rather than measured, while photo-based strip reading remains disabled pending laboratory-reference testing.
