ReefCtrl started as a personal project to solve a simple problem: keeping track of a reef tank shouldn't require spreadsheets, multiple apps, and constant manual logging.
Running a reef tank involves tracking dozens of parameters, scheduling regular maintenance, interpreting ICP results, identifying new livestock, and making dosing decisions — all while hoping nothing goes wrong overnight. Existing tools were either too simple or required expensive dedicated hardware.
ReefCtrl integrates directly with the controllers serious reef keepers already own — Neptune Apex, Focustronic, and CoralVue Hydros — and brings ICP results and manual logs into the same place. Combined with AI analysis, it turns raw data into actionable insight. No new hardware required, no complicated setup.
We connect to your Neptune Apex straight through Apex Fusion, Neptune's own cloud. No dedicated hub device, no desktop agent, no port forwarding — you sign in once and your tank syncs from anywhere, with instant outlet control.
We're working on deeper AI capabilities — including proactive personalised insights that surface problems before they escalate. We're building in public, taking feedback from early users seriously, and shipping fast. The iOS app is live on the App Store now.
We'd love to hear from you — feedback, feature requests, or just to say hi.
