What to check before you act

Before changing the setup, record the tank size, equipment, livestock, current water condition, and the part of the routine that must become easier. A workable setup is one the keeper can repeat and inspect.

Decision boundary

The recommendation changes when the tank condition, livestock, equipment, or maintenance capacity changes. If the observed problem falls outside this page’s scope, stop at the boundary, collect the missing measurement, and use the related guide before acting.

Recheck: Recheck after the next maintenance cycle or after one variable changes. Record the date, the observed result, and the evidence that supports the next decision.
