Coming 2026 Tidevue · The reef controller

The reef controller that just works.

One input: your tank size. Everything else is automatic — temperature control, alerts, and peace of mind.

The Tidevue way

Built for reef keepers, not engineers.

Every other reef controller treats configuration as a feature. Tidevue treats it as an admission of failure. Tell us your tank size, follow a visual placement guide, and the rest is researched, validated, and automatic.

The problem

Reef controllers are built for engineers, not reef keepers.

Three patterns repeat across every other controller on the market.

01 / Friction

Endless configuration

Other controllers require hours of setup — sensor naming, threshold configuration, network settings, calibration routines.

Neptune Apex: 50+ settings just for temperature.

02 / Friction

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.

GHL Profilux: 400-page manual.

03 / Friction

Alerts that fail

When the power goes out, your WiFi goes with it. Your “smart” controller can’t reach you when it matters most.

Every other controller relies on WiFi.

How it works

Setup in under two minutes.

Seriously. Three steps from box to monitoring.

01

Enter your tank size

75 gallons? 120 gallons? That’s all we need to know.

One input. That’s it.
02

Follow the visual guide

Clear diagrams show exactly where to place sensors and the heater. No guessing.

We did the research.
03

Done. It just works.

Optimal temperature, duty cycle, and safety thresholds calculated automatically.

78°F. Perfectly maintained.
Configuration is not a feature. It’s an admission of failure.
Tidevue design philosophy
Features

Everything you need. Nothing you don’t.

Six pieces of hardware and software, designed to disappear once they’re working.

F / 01

PWM heater control

500W titanium element with precision duty-cycle control. Maintains ±0.1°F accuracy without temperature swings.

F / 02

Native iOS app

Built specifically for iPhone and iPad. No web wrapper — real native SwiftUI with beautiful animations.

F / 03

HomeKit integration

See your tank temperature in the Home app. Works with Siri and automations out of the box.

F / 04

Multi-layer safety

Software limits, hardware cutoff, and dual sensor validation. Your tank is protected even if software fails.

F / 05

Research-backed defaults

78°F target, 82°F emergency cutoff, optimal placement guides — all based on reef science, not guesswork.

F / 06

Real-time monitoring

WebSocket-powered live updates. Watch your temperature in real-time with 30-minute historical sparklines.

Industry first

Still works when everything fails.

When the power goes out, your WiFi goes with it. Every other controller goes silent at exactly the moment you need it most.

Tidevue includes an integrated cellular module with its own battery backup. Even during a total blackout, you’ll get alerts on your phone in seconds.

  • Built-in LTE cellular with battery backup
  • Alerts sent during power + internet outages
  • No monthly fees for basic alerts
  • Optional premium monitoring subscription
