Poolwright turns your pool or spa test readings into clear amounts to add. Enter free chlorine, pH, total alkalinity, calcium hardness and stabilizer (CYA), then see the dose for the products you own.

CALCULATE WITH CONFIDENCE
• Liquid chlorine, cal-hypo, dichlor and trichlor
• Muriatic acid, baking soda, stabilizer and calcium chloride
• Metric or US units
• Pool volume from rectangle, round or oval dimensions

Always follow the product label. Add chemicals to water, never water to chemicals, and never mix chemicals together. For pH adjustments, add about 75%, circulate and retest before adding more.
