Intelligent reef
management.

ReefCtrl brings your Apex, Hydros, Focustronic, Red Sea and ICP tests into one dashboard — then adds an AI reef expert that knows your exact tank: it reads your water, interprets your ICP results, spots disease from a photo, and flags problems before they escalate.

The difference

Not just a dashboard.
An AI reef expert.

Other apps show you numbers. ReefCtrl understands them — every answer grounded in your exact tank, your livestock, and your history. This is what you can’t get anywhere else.

Knows your exact tank
Ask anything. The assistant reads your live parameters, livestock and equipment and answers grounded in your data — not generic forum advice or a chatbot that’s never seen your reef.
Reads your ICP tests
Upload a Triton, ATI or Fauna Marin report and get instant analysis — out-of-range elements flagged and specific dosing adjustments recommended in seconds, no chart-squinting.
Spots disease from a photo
Snap a struggling fish and AI checks for ich, velvet, flukes, Brooklynella and more — then builds a treatment and quarantine plan you track day by day, with a built-in copper dosing calculator.
IDs fish & coral instantly
Not sure what you just added? Photograph it and AI names the species — fish or coral — and drops it straight into your livestock registry with its care profile.
Tackles pests & algae
Aiptasia, flatworms, dinos, cyano, bryopsis — describe what you’re seeing and the AI gives a tank-specific plan to get rid of it, weighing what’s safe for your livestock.
Catches problems early
AI watches your trends and surfaces issues — a slow alkalinity drift, a stalling doser, a controller gone quiet — with personalised insights before they turn into a crisis.

How it works

Live in five minutes

No hardware to buy, no network setup. Connect your gear and ReefCtrl does the rest.

1
Connect your gear
Link Apex Fusion, CoralVue Hydros, Focustronic or Red Sea in a couple of taps — or just log parameters by hand. No controller required.
2
We sync around the clock
ReefCtrl pulls your parameters, outlets and dosing 24/7 in the cloud, so your tank’s live data is always a tap away — wherever you are.
3
Act with confidence
AI analysis, smart push alerts and weather warnings tell you what’s changing and what to do — before it becomes a problem.
Platform

Everything your reef needs

Built for serious reef keepers who want data-driven decisions, not guesswork.

One platform
Every device in one dashboard
Neptune Apex (Fusion), CoralVue Hydros, Focustronic Alkatronic & Mastertronic, Red Sea ReefMat, ICP tests and manual logs — all syncing into one source of truth. No exports, no spreadsheets, no app-switching.
Live monitoring
Every parameter, always current
Temperature, pH, alkalinity, calcium, salinity, ORP and more — auto-synced from your controllers with trends and history. Apex extras too: sensors, Trident reagent levels and DDR containers.
AI assistant
A reef expert that knows your tank
Ask anything. The assistant reads your real parameters, livestock and equipment, and answers grounded in your data — not generic advice.
Smart alerts
Catch problems before they escalate
Push notifications when pH drops, alkalinity drifts, a doser runs low, or a controller goes offline — with smart cooldowns so you’re never spammed.
