The reef controller
that just works.
One input: your tank size. Everything else is automatic.
Temperature control, alerts, and peace of mind.
Reef controllers are built for engineers,
not reef keepers.
You got into this hobby to enjoy your tank, not to become a systems administrator.
Endless Configuration
Other controllers require hours of setup. Sensor naming, threshold configuration, network settings, calibration routines...
Manual Required
You need to read a manual just to know where to put your sensors. Trial and error isn't an option with live coral.
Alerts That Fail
When your power goes out, so does your WiFi. Your 'smart' controller can't reach you when it matters most.
Setup in under 2 minutes.
Seriously.
We believe the best technology is invisible. You shouldn't need to think about your controller—it should just keep your tank perfect.
Enter your tank size
75 gallons? 120 gallons? That's all we need to know.
Follow the visual guide
Clear diagrams show exactly where to place sensors and heater. No guessing.
Done. It just works.
Optimal temperature, duty cycle, and safety thresholds are all calculated automatically.
"Configuration is not a feature.
It's an admission of failure."
— Tidevue Design Philosophy
Everything you need.
Nothing you don't.
PWM Heater Control
500W titanium element with precision duty-cycle control. Maintains ±0.1°F accuracy without temperature swings.
Native iOS App
Built specifically for iPhone and iPad. No web wrapper—real native SwiftUI with beautiful animations.
HomeKit Integration
See your tank temperature in the Home app. Works with Siri and automations out of the box.
Multi-Layer Safety
Software limits, hardware cutoff, and dual sensor validation. Your tank is protected even if software fails.
Research-Backed Defaults
78°F target, 82°F emergency cutoff, optimal placement guides—all based on reef science, not guesswork.
Real-Time Monitoring
WebSocket-powered live updates. Watch your temperature in real-time with 30-minute historical sparklines.
Still works when
everything fails.
When the power goes out, your WiFi goes with it. Every other controller goes silent exactly when you need it most.
