Field notes
Visitors can choose among ten linked calculators, from pool volume and salt additions to pH, calcium hardness, and hot-tub chlorine or bromine. The page says these browser tools are free and require no sign-up; its separate test-strip workflow is described as an iPhone app still awaiting App Store launch. DipDose says strip photos stay on the phone and advises that product labels take precedence.
