Exo-ATO by Reef Breeders is one of the premiere ATO systems with self-contained electronics that are externally mounted to reduce damage caused by water or moisture while allowing easy installation and access. The compact controller and sensor have a small 1/2" thick x 1” diameter mounting magnet leaving only a small footprint on the wetside of the sump. The Exo-ATO unit is designed for glass or acrylic sumps.

Being a self-contained ATO unit, The Reef Breeders Exo-ATO houses the controller and sensor in a compact design. The quick and simple setup utilizes only 2 power cords which further add to ease of installation and effort with minimal equipment to reduce clutter and allow for more space inside the sump.

Every Exo-ATO has a computer onboard with several built-in safety features which are listed below:

• Frequency Alert: The system will beep to notify you that your aquarium has not been topped off for an unusual amount of time, at least 24 hours and double the average time between Top Off. Ex: if the Avg. time between topping of is 12 hours, the system will notify you after 24 hours of not topping off.
• Overfill Alert: The system develops and average time that the pump is running each time the system is activated. If the system detects that liquid has been dispensed for more than 3x that average baseline time, it will shut the pump off and create an audible alarm.
• Empty Reservoir Alert: The system can detect when the top off pump is drawing excess air/running dry and automatically shut the pump off and create and audible alarm.
• Sensor Obstruction Alert: The system will detect if the in-tank sensor needs to be cleaned, is being obstructed, or is out of alignment. This is denoted by a flashing blue light.

The Reef Breeders Exo-ATO is ready to go out of the box! Simply install the system in the aquarium sump whether it be glass or acrylic up to 0.20 inches (5mm) thick. The Exo-ATO kit includes the sensor/magnet assembly, DC power supply, pump, tubing and tubing bracket that fits most sumps.
