Everything your reef needs

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

One platform
Every device in one place
ReefCtrl consolidates your whole system — Neptune Apex via Fusion, Focustronic Alkatronic and Mastertronic, CoralVue Hydros, ICP labs, and manual logs — into a single dashboard. Apex syncs continuously and Focustronic auto-syncs on its own, so every reading lands in one source of truth without exports, spreadsheets, or app-switching.
Live monitoring
Every parameter, always current
Temperature, pH, alkalinity, salinity, ORP and more — auto-synced from Apex Fusion. Float switches, optical sensors, and liquid level sensors displayed live. Trident ACM and NP reagent levels and waste container monitoring included.
Outlet control
Control your Apex from anywhere
Switch outlets on, off, or auto right from the app — including virtual outlets you created in Apex. Total system wattage and per-outlet power draw at a glance.
Dosing tracker
Never overdose or miss a dose
Track Fauna Marin Balling, ESV B-Ionic, Kalkwasser and more. Monitor Neptune DDR container levels live. Log doses in one tap — no typing.
Reef calculators
Dose and convert with confidence
A full calculator suite built in — alkalinity, calcium and magnesium dosing across 100+ named products, salt mixing, salinity (SG ↔ ppt), nitrate and phosphate raise-and-lower, and 18 trace elements. Pick your product, set a target, get the exact dose — prefilled from your tank volume and latest tests, with safe-step guardrails so you never shock the system.
ICP analysis
Lab results, instantly interpreted
Upload your Triton, ATI, or Fauna Marin ICP report and get AI analysis in seconds. Out-of-range elements highlighted, dosing adjustments recommended.
AI assistant
A reef expert in your pocket
Ask anything about your tank. The assistant knows your exact parameters, livestock, and equipment — and gives answers grounded in your real data.
Apex code generator
Write Apex programs with AI
Generate Apex Fusion programs using plain English. Describe what you want and get ready-to-paste code using your actual outlet and probe names.
Smart alerts
Catch problems before they escalate
Push notifications when pH drops, alkalinity drifts, dosing containers run low, or Apex goes offline. Intelligent cooldowns stop alert fatigue.
Livestock registry
Know every animal in your tank
Track fish and coral with species notes, health status, and care history. AI identifies species from a photo so nothing slips through the cracks.
Equipment & maintenance
Stay on top of every task
Log your equipment, set recurring maintenance schedules, and get reminders before tasks go overdue. Swipe to complete or reschedule.
Works without Apex
No controller? No problem.
Manually log water parameters and get full AI analysis, trend charts, ICP insights, dosing tracking, and maintenance reminders — no Apex required.
Integrations
Focustronic auto-sync
Connect your Alkatronic and Mastertronic once — ReefCtrl pulls every new test automatically: alkalinity, calcium, magnesium, nitrate, nitrite, phosphate, flow straight into your parameters. No exporting, no re-typing, no separate app to check.
Integrations
Hydros controller support
Connect a CoralVue Hydros controller and see your probes, outlet states, operating mode, and device health in ReefCtrl. Readings auto-log to your dashboard and history alongside the rest of your reef.
