What the source gets right

It prioritizes setup sequence before advanced upgrades.
It pushes consistency over constant tweaking.
It frames patience as a system requirement, not a personality trait.

What is missing or risky

New reefers still need clearer conflict rules for mixed test results.
Contingency steps for missed maintenance weeks are limited.
Stocking pace risk after first “good week” is underplayed.

Beginner 90-day checklist

Stabilize salinity and temperature first.
Run one maintenance cadence for at least two weeks before changing anything.
Add livestock in stages, not bundles.
Track weekly trends in parameters and behavior.
Make one major adjustment at a time.

Build your equipment and livestock plan with shop search, compare basics like heater and skimmer, then log your routine in the ReefBay app so changes stay measurable.
