Field notes
The page lists six tracked measures—pH, nitrite, nitrate, ammonium, GH, and KH—and says records can be grouped by tank, alongside water changes, fertilizer, and filter care. Its proposed camera reading shows a suggested value for user confirmation rather than silently recording a result. A printable A4 calibration card is linked; the site says a small reference strip helps reduce room-light effects.
