GuidedReef understands your setup, livestock, goals, and maintenance style — and tells you what to do next. Not a spreadsheet, an assistant.
40 gallons · Moderate maintenance
Biological algae control
Bubble algae detected. Emerald crabs are reef-safe and a good fit for your 40B setup.
Dosing optimization
Alkalinity swings suggest inconsistent dosing. Try smaller daily doses for better stability.
What it does
Track reef, planted, freshwater, shrimp, and quarantine tanks side by side.
See parameter movement over time and catch issues before they impact livestock.
Setup-aware advice that explains why — based on your goals and effort level.
We won't recommend jumpers if your tank has no lid, or coral nippers if you have coral.
Log water changes and dosing — and see how they correlate with parameter trends.
Tell us your effort level. We'll tune recommendations from minimal to high involvement.
