Field notes
Pool setup fields include volume, surface material, and chlorine source, with optional tracking for salt and borates. Spreadsheet imports require a Date column, accept alternate names such as “Free Chlorine,” and can retain rows containing only notes. The page cautions that doses are estimates and recommends circulating and retesting before adding more.
