Why PoolCalc
Pool chemistry is mostly arithmetic that nobody explains well. Get the volume right and the rest follows: salt, chlorine, stabilizer, and the rest are just doses per gallon. These calculators give you the number and show the reasoning, so you treat the water once instead of chasing a cloudy pool all weekend.
