Diagnose your reef tank before you lose a coral.
Photograph the affected coral, fish, or rock. Reef Doctor AI checks against common reef tank problems — bleaching, brown jelly, RTN, parasites, water quality issues — and tells you what to test, what to dose, and what to remove from the tank.
Coming soon. Reef Doctor AI is in active development. Email hello@crate-app.com for early access.
What Reef Doctor AI does
Photo + water params = diagnosis.
Photograph the problem and enter your latest test readings (alkalinity, calcium, magnesium, phosphate, nitrate, temperature, salinity). Reef Doctor AI weighs photo evidence against water quality to narrow down the cause.
Recovery protocol per problem.
For bleaching: shade, stable params, no chasing numbers. For RTN: fragmenting the healthy tissue. For dinoflagellates: the full UV/blackout/dosing protocol. Every protocol has the steps in order with timing.
Water-chemistry trend tracking.
Log your daily/weekly test readings. Pro shows trend lines for every parameter and flags when something is drifting before it causes visible problems.
Quarantine and dipping protocols.
For new coral, fish, or invert additions: Power Pro's guided quarantine + dipping protocols (Bayer Advanced, ReVive, ICP test routing) reduce the chance of introducing pests to your display tank.

What we don't do
- We are not marine biologists. Reef Doctor AI surfaces patterns based on community-documented protocols; for unusual or persistent issues, post to a reef forum (Reef2Reef, UltimateReef) with photos.
- We do not share your tank data.
- We do not store your name. Your tank is keyed to an anonymous account.
