- Its dosing guidance orders alkalinity, pH, slow-moving calcium and stabilizer, then chlorine, to avoid chasing corrections.
Field notes
Setup asks for pool or hot-tub type, volume, sanitizer, surface, and usual chlorine product, then applies those settings across the calculators. The chemistry guidance distinguishes fast adjustments from slower-moving calcium and stabilizer, and advises testing free chlorine and pH more often than other measures. The page also cautions that its information is general guidance, not professional advice.
