Your tank’s paper trail

Keep the details you might need later.

A clear history helps you explain what was used and when. Keep the bottle and label details alongside your observations.

Record what happened after it happened. There are no suggested treatments, calculated doses, repeat-dose reminders or automatic schedules.

What to check

Write the exact product, formulation, water volume basis and event time. Describe an observation as seen or measured, including the test and units.

Worked situation

“Test read 0.2 mg/L at 18:30” is an observation. “Treatment caused the result” is a hypothesis and belongs on a separate line with its evidence gap.

What to record next

Download the log before clearing browser data or moving devices. A local save is not a shared file; update the handover separately when someone else takes over.
