The Reef Breeders Exo-ATO (External ATO) is one of the first ATO systems to contain all electronics outside of your aquarium. The controller and sensor mount to the outside of the glass, and a small magnetic ring is inserted at your desired water level. That leaves only a 1/2″ thick x 1″ diameter ring inside your sump, so it will fit easily in clear acrylic or glass sumps!
The Reef Breeders Exo-ATO is fully self-contained, meaning the controller, sensor, and backup functions are all contained in one small central unit. There is one plug for power in, and another plug for power out to the pump (included). That’s it. No more controllers to mount in your aquarium stand, and no more obtrusive sensors in your sump!
Every Exo-ATO has a computer onboard with several built in safety features which are listed below:
The Reef Breeders Exo-ATO includes everything you need to get started- Just add water! The Exo-Ato system includes the sensor/magnet lens pair, a small dc power supply, a pump, tubing, and a tubing holder that fits most sump trims. They can also be used in the return chamber of all in one aquariums 20g or larger. Designed for clear glass or acrylic up to 0.20 inches (5mm) in thickness.
