Field notes
The site pairs its cycle explanation with calculators for tank volume, stocking, cycle timing, and water changes. Its FAQ gives threshold-based guidance for fish already in an uncycled tank, including a 30–50% water change at 0.25 ppm ammonia or nitrite and an immediate change at 1 ppm. The companion app is described as in development; its advertised features include test charts, species information, and reminders.
