Red Sea- ReefATO+ Auto Top Off System

Red Sea ReefATO+ System – Smart Top-Off Tech for Stable Reef Tanks

The Red Sea ReefATO+ System takes the stress out of maintaining stable water levels in your reef tank. It keeps salinity in check, protects your coral investment, and helps you avoid those "oh no" moments when evaporation sneaks up on you.

Whether you’re just starting your reef journey or you've got a tank full of SPS that cost more than your car insurance, this system steps in like a silent assistant—always watching, never missing a beat.

Advanced Features of the Red Sea ReefATO+ System

This ATO isn’t just a water filler. It’s a full-blown reef assistant.

• Smart ATO Control – Automatically tops off evaporated water to maintain salinity balance.

• Built-In Temperature Monitoring – Logs accurate readings and alerts you through the ReefBeat App.

• Leak Detection – Instantly stops the pump and sends alerts if it detects water where it shouldn’t be.

• ReefBeat App Integration – Control the entire system from your phone, including notifications and logs.

Reliable Water Level Monitoring of the Red Sea ReefATO+ with Dual Sensors

The ReefATO+ uses a dual-sensor water level probe for precise monitoring. One sensor keeps your levels consistent; the second steps in as backup.

• Prevents overfilling with backup shutoff

• Tracks water level in real time through the app

• Designed to work with RO/DI water systems

This means you can enjoy your tank—not babysit it.

Built-In Temperature Sensor for Stability

Temperature swings stress corals, but this system has your back. The built-in sensor tracks fluctuations and provides accurate logs every 15 minutes.

• Monitors temperature with ±0.1° accuracy

• Logs history for up to 28 days

• Sends alerts if your tank temp drifts out of range

Set your range in the app once, and let the system handle the rest.

Quiet, Smart ATO Pump Included

The included 12VDC pump is compact, quiet, and smart enough to know when to stop. No gurgling, no mess—just clean, automated refills.

• Flow rate: Up to 75 GPH

• Max head height: 8 feet

• Auto shutoff when dry or disconnected

• ReefBeat alerts if something goes wrong

It’s like the Tesla of ATO pumps—silent, smooth, and way smarter than it looks.

Red Sea ReefATO+ - Reef-Spec Leak Detection for Safety

Things go wrong. That’s why the Reef-Spec leak detector is such a game-changer. It disables auto-filling immediately and alerts you the second water goes where it shouldn’t.

• Detects leaks from RO or saltwater sources

• Sends instant alerts to the ReefBeat App

• Can shut down other ReefBeat devices during emergencies

If your tank tries to flood your floor, this system stops it before you grab the towels.

Smart Controller with ReefBeat Ecosystem Integration

The controller connects every component and gives you a full dashboard of your tank’s top-off behavior.

• Displays fill history, water levels, and temp logs

• Compatible with the entire ReefBeat product line

• Sends push notifications for all important updates

You’re basically getting a reef-tech command center.
