Reef Breeders Exo-ATO

Super compact and ultra-intelligent. Great for maintaining the water level in small and large tanks alike.

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 aquarium, so it will fit in pump return chambers large and small!
