Frequently Asked Questions
Clear answers to common pool chemistry and calculation questions.
How do MyPoolLab calculators determine chemical dosages?
Our calculators use standard stoichiometric chemical formulas calibrated to National Swimming Pool Foundation (NSPF) and APSP guidelines. We calculate exact chemical masses based on active ingredient concentrations (such as 12.5% sodium hypochlorite, 31.45% muriatic acid, and 99.8% sodium chloride).
Why do I need to calculate my pool volume first?
Virtually all chemical instructions on pool chemical bottles are prescribed per 10,000 gallons (or liters) of water. Without knowing your water volume, any chemical addition is a guess, which leads to chronic under-sanitization or chemical overdosing.
Do these calculators work for both saltwater and traditional chlorine pools?
Yes. We provide specific calculators for saltwater chlorine generators (including salt ppm and bag calculations) as well as traditional liquid chlorine, cal-hypo shock, and stabilizer balancing tools.
