First decision

Cycle and commission a shrimp tank

You need to decide whether a new or changed system is ready for shrimp.

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 the complete system, current nitrogen results, test resolution and whether conditioned media and surfaces are actually present.

First action

Run the documented nitrogen-processing challenge before livestock arrive rather than using tank age, appearance or a product label as readiness.

Record next

Record the added challenge, reporting basis, elapsed time, ammonia and nitrite results, temperature, pH and any intervention.

Stop boundary

Do not add shrimp while the intended load is not processed at the declared test resolution or while the system is still changing.
