Public BetaEvery paid feature is unlocked at no cost until 31 December 2026 — no card, in exchange for your feedback.

The assistant

Advice is only as good as its context. So we hand it the context.

Ask a forum why your acros paled and you will get forty answers from people who have never seen your tank. This assistant is handed your measurement history, livestock list, equipment, dosing and maintenance log before it responds — and it shows you which readings it leaned on.

Chat with your history

"Has my phosphate ever been this high?" and "what changed the week my monti bleached?" are answerable questions here.

Photo diagnostics

Photograph a struggling coral and get a read on what the tissue is actually doing — recession, bleaching, STN, or pest damage.

Pest & hitchhiker ID

Flatworms, red bugs, sundial snails, vermetids, bristleworms, aiptasia. Identify it before it becomes a project.

It cites its sources

Every substantive answer names the measurements it used and the window it looked at. If you disagree, you can go and check — the reasoning stays open, because your own tank is the last place to take a chatbot on faith.

It is also allowed to admit uncertainty. When your data is too thin to support a conclusion, it tells you what to log.

Unlocked during Beta

Every Beta member gets the full assistant, photo diagnostics and ICP interpretation at no cost. After Beta the free plan includes 20 assistant actions a month, Reef+ raises that to 200, and Pro to 500.

Should I do a water change this weekend?
Probably not yet. Your nitrate is already at 2.1 ppm and falling — a 20% change would take it under 2, and your acros are showing colour loss consistent with nutrients that are too low.

Copper at 0.009 is the one exception, and a water change is a slow fix for that; a poly-filter would be faster.Read from 61 measurements + ICP of 14 Jun
What dose gets me to 5 ppm?
Your 240 L system at 2.1 ppm needs roughly 0.7 g of sodium nitrate to reach 5 ppm in one hit — but split it over 5–7 days so the swing is gentle, and re-test on day 4.Calculated from tank volume 240 L
