Drift you'd have missed

What that looks like in practice
ICP results that mean something
Your ICP report says phosphate is below optimal. MyCeto knows whether this is the cause of your nuisance algae or not. That's the difference between a number and an answer.
Advice that knows your tank
Ask a question and get an answer about your system — your volume, your salt, your livestock, your history — with the marine science behind it cited, every time.
What MyCeto is
One structured model of your aquarium system
Build a model of equipment, topology, containers, volumes, livestock, dosing, consumables, and chemistry. Each app reads from the same source of truth, so the platform behaves like one connected whole.
Build a reliable source of truth
Capture the shape of the real aquarium once, then let every app reuse that context instead of re-entering details in separate tools.
Know what needs attention
Use messages, reminders, tests, dosing plans, livestock records, and trends to keep routine work visible.
Ask better questions
MyCeto AI can answer from controlled references, with the twin available to add context where your tier allows it.
Apps at a glance
Five live apps around your aquarium twin
Live
Systems
Model your aquarium, sump, equipment, plumbing, power, data topology, and effective volume so every other app understands your system.
LiveDosing & Testing
Dosing products & plans, manual water tests, ICP imports, defined and user defined range flags, and trend charts live together in Dosing & Testing.
LiveLivestock & Feeding
Track inhabitants by container, check compatibility before adding stock, and keep feeding and livestock history in the twin.
LiveAI
Ask questions against manufacturer data and expert-authored scientific references, with citations and tier-aware system context.
LiveTelemetry
Telemetry brings read-only sensor data into the twin and AI context over secure provider APIs. The app is live now; manufacturer integrations are agreed individually, and the Integrations page shows where each one stands.
