- The page says last week’s readings are pre-filled, while reminders surface overdue work on a per-tank basis.
Field notes
The described entry flow starts by selecting a tank, then choosing tested parameters; last week’s values are pre-filled so keepers change only readings that differ. Logs include custom readings and can be searched, while maintenance schedules cover water changes, filter cleaning, siphoning, top-offs, and dosing. The page says the free tier covers one tank; its one-time unlock adds multi-tank tracking, trend charts, and CSV export.
