How to use this part of Reefly

1. Upload a clear photo and provide your latest readings so the check summary matches what you are seeing.
2. Link each report to the correct tank so your tank timeline, routines, and partner picks stay accurate.
3. Execute recommendations in priority order, then wait long enough for measurable response.
4. Re-run checks after intervention and compare report progression before introducing new variables.

Get the most out of it

• Keep photo angle and lighting similar across follow-ups to improve trend comparisons.
• Do not stack multiple chemical changes in one day unless life safety is at risk.
• Use report history as evidence when escalating to experts.
