Version: 1.0
Reviewed: 2026-08-12
Topic: Read ammonia, nitrite and nitrate correctly

Situation: Ammonia, nitrite or nitrate is being used to judge readiness or a change.
Observe first: Identify the analyte, reporting basis, unit, test resolution, pH, temperature, recent feed and recent livestock or filter changes.
First action: Confirm the result and protect animals from a continuing measured hazard while investigating source and system function.
Record next: Record exact analyte and basis, method, before and after values, pH, temperature, actions, deaths and recovery observations.
Stop boundary: Do not equate TAN with un-ionized ammonia, use one nitrate result as proof of cycling or invent a universal chronic safe threshold.
