Study context
Weekly kit readings from one pond. Values reflect total ammonia as measured by the kit, not un-ionised ammonia, and there was no untreated control.
How it was measured
- API aquarium-style test kit, readings taken weekly.
- Source: internal Ecofresh test report, pp. 22–25.
What this does not show
- No untreated control pond.
- Colorimetric kit readings, not laboratory analysis.
- Internal observation — not independent, not peer reviewed.
