Red Sea ReefATO+

Red Sea ReefATO+

The Red Sea ReefATO+ is an advanced auto top-off (ATO) system that does more than just replenish evaporated water. With built-in temperature monitoring, a leak detector, and app connectivity, it offers next-level automation and security for your reef aquarium.

Key Features:

Ultra-Reliable Water Level Sensor

• Features a backup sensor to prevent overfilling.
• Multiple probes provide real-time water level data via the ReefBeat App.

Precision Temperature Monitoring

• Integrated pre-calibrated temperature sensor with ±0.1° accuracy.
• Set desired and acceptable temperature ranges in the ReefBeat App.
• Get instant notifications if the temperature exceeds the set limits.
• View detailed 28-day temperature logs, including min/max/average values.

Smart & Quiet ATO Pump

• Variable-speed, 12V DC pump with a compact 1.8” diameter, perfect for tight reservoir spaces.
• Max flow rate: 75 GPH, max head: 8 feet, power: 6-10W.
• Automatically adjusts flow to maintain a quiet, splash-free 18 GPH rate.
• Built-in pump performance monitor alerts you if the pump stalls, disconnects, or if the reservoir runs dry.
• Noise-dampening impeller chamber ensures ultra-quiet operation.
• Includes a secure locknut outlet connection for leak-free tubing attachment.

Reef-Safe Leak Detector

• Highly sensitive titanium probes detect both saltwater and RO/DI water leaks.
• If a leak is detected, the ATO is immediately disabled, an audible alarm sounds, and a notification is sent to your phone.
• Integrates with the ReefBeat ecosystem to automatically shut down return pumps and other connected devices in case of an emergency.

Smart Controller & ReefBeat App Connectivity

• Monitor water level, top-off history, and temperature trends over the last 28 days.
• Customize settings and receive real-time alerts if anything goes wrong.
• Seamlessly integrates with other Red Sea smart devices for a fully connected reef system.

• Magnetic sensor holder (fits glass up to 12mm/½” thick)
• 10′ of silicone tubing
• Silent flow tube holder (clips onto 4-12mm/½” glass)
