Ammonia tracked from setup through to consecutive zero readings.
How does ammonia from fresh aquasoil decline under a heavy water-change schedule?
Fresh active aquasoil releases ammonia for a period after setup. The standard advice is heavy water changes tapering after a few weeks, but the actual duration varies and is rarely published as a measured curve.
Ammonia would peak in the first days and decline steadily, reaching zero somewhere around the fourth week under an every-other-day change schedule.
Recorded before measuring, so it can be shown to have been wrong.
Ammonia is hand-tested on a repeating schedule and logged against every water change, so the decline curve and the change cadence can be read together.
