THE CHAT

An assistant that has read your tank before you ask.

It answers from your readings, doses, livestock and notes, checks facts against a curated reef reference, and does the record keeping for you.

THE CHAT

Forum advice is about a tank. This is about yours.

Before it answers, ReefGPT reads your recent readings, your doses, your livestock and your notes. Its answers quote your actual numbers, so you can check them against the tank.

Yes. Alkalinity has slid from 8.4 to 7.0 dKH over 30 days while DosAlk held steady at 54 mL a day, so the tank is using more than you add, and it is now below the 7.8 to 9.5 target for your tank. The two acro frags you noted on Sep 16 will only add to that.

Raise DosAlk by about 10%, to 60 mL a day, and let the Trident confirm it over three days before going further. Bring it back up slowly, no more than about 1 dKH a day.

Ask about your tank…
IT DOES THE PAPERWORK

Tell it what you bought. It files it.

Mention new livestock, something that happened, or a reminder you want. It checks a new animal against your tank and the species reference, prepares the change, and waits. Nothing is written to your tank until you tap Confirm.

Say only “a blenny” and it asks which one first, because a lawnmower and a tailspot are very different fish.

WHY IT GETS IT RIGHT

Built to be right about your tank, not just fluent about reefs.

A general chatbot answers from what it absorbed about reefs in general. This one reads your tank first and checks facts against a reference built for the hobby.

01Specialist agents, not one guessEach question goes to the specialist agents it needs: one reads your live readings, one your tank's history, one your equipment, one the reef knowledge base. They report back, and only then is your answer written, with your own numbers in it.
02A curated reef knowledge baseHusbandry guidance written for reefkeeping, plus a reference of 377 species with minimum tank size, adult size, temperament and reef safety. Facts are looked up there, not recalled from whatever a model half-remembers.
03Grades the chat cannot changeTank condition comes from fixed rules, so the same readings always get the same grade. The chat reads that grade and explains it. It cannot invent one, and it cannot talk you out of one.
04Nothing changes without youAnything that writes to your tank, like new livestock, an event or a reminder, is shown to you first and waits for Confirm.

How the agents are coordinated is our own work, so we keep those details to ourselves. What they read is always yours.
