The ATO Controller is a smart device that mounts magnetically and uses an Optical Infrared sensor to monitor water height. Simply mount the ATO Controller to the tank or sump chamber at the desired water height within your Aquarium or sump filters return pump chamber. As the water level drops the ATO Controllers optical sensor detects this triggering the return pump mounted in a reservoir to replenish the water in the system. When the water level reaches the set height the optical sensor triggers the pump to stop.
ATO Controller is a simple to use intelligent Auto Top Off system that is a handy addition to any Aquarium.
