ATO Auto Top Off System NexGen11 for Saltwater Aquarium Seamless Design with Dual Optical Sensor for Both Reef and Fresh Tanks

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!.
