First decision

Run filtration, oxygen and flow

You are selecting or troubleshooting filtration, aeration, flow or an intake.

Use the whole card. The action stays attached to what must be observed and recorded, plus the nearest inference or action the current guidance cannot support.

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.
