Field notes
The dose check accepts tank volume in liters or gallons and test results in several common formats, then returns an amount and a schedule. The page says product entries include manufacturer directions, cautions, and sources; it also gives a worked 400 L alkalinity example and lists limits for alkalinity, calcium, and magnesium. The test log, forecasts, and consumption estimates are presented as Plus features.
