Version: 1.0
Reviewed: 2026-08-12
Topic: Run filtration, oxygen and flow

Situation: You are selecting or troubleshooting filtration, aeration, flow or an intake.
Observe first: Check water movement, surface agitation, intake protection, conditioned media, power state, debris load and animal behavior around the device.
First action: Protect intakes, preserve wet conditioned media and restore oxygen and circulation safely before changing several system variables at once.
Record next: Record equipment state, outage duration, temperature, oxygen measure when available, nitrogen results, cleaning method and animal response.
Stop boundary: Do not treat a manufacturer flow rating as biological capacity or assume visible bubbles prove adequate oxygen everywhere in the system.
