The aquarium intelligence platform for serious reefers — and the kid who won't stop asking why the clownfish lives in the anemone.
Dark UI. Glanceable data. Real chemistry guidance. And biology your kids will actually want to learn.
Live parameter cards with green/orange/red status, real-time charts for Alk, Ca, Mg, Temp, and Salinity — everything at a glance, optimized for dark tank rooms.
The goby and pistol shrimp. The clownfish and anemone. The neon goby's dental clinic. Explained in plain English — and in kid-friendly language that sticks.
11 common reef pests with Wikipedia photos, ID tips, and treatment guides. Know exactly what's on your coral before it spreads.
37 animals ranked by value. Zoanthids, Kenya Tree, Neon Gobies — the animals that make new reefers fall in love without emptying their wallet.
Tolerable, natural ocean, and notes columns. Dosing guidance and alerts when chemistry drifts — backed by BRS values, not guesswork.
Add gear from Red Sea, Waterbox, EcoTech, Kessil, and AI in seconds. Track your full setup in one place.
ReefCMD costs less than
one dead clownfish.

Green/orange/red occupies the top border of every parameter card. One glance from across the room tells you if something needs attention.
Always visible on every screen. Logging a reading should never require more than 2 taps — this is the most-used action on mobile.
Alerts appear inline as persistent strips. They don't hijack the screen — they stay visible so you can reference them while logging.
The kid-friendly bio fact lives right on the home screen. Rotating daily. "The clam is farming sunshine" isn't a detail — it's a hook.
Pre-populated from last reading. Large tap targets. Numbers only. Submit in under 10 seconds — even with wet hands.
