ATO Controller

Our compact electronic controller is easy to mount out of sight. An optional audible chime alerts you when in operation mode.

Float Sensors

Dual float sensors activate within seconds of detecting a change in water level, and an exterior guard protects sensors from snails.

Multi Mode

With two operating modes to choose from and dual float sensors, it’s easy to customize the JBJ ATO Kit to suit most aquarium and sump set-ups.

Safe Stop

Float sensors automatically stop power to your return pump in the event that your reservoir is low on water, and a built-in timer prevents overfilling.

Optically Accurate

The included protective cover prevents tank inhabitants from covering the optical sensor. Additionally the protective cover reduces sudden changes in light or water surface disruption from affecting the sensor. This ensures accurate water level measurements every time.

The complete waterproof design allows the sensor to be mounted virtually anywhere. The magnetic mount can hold securely up to 15 mm glass thickness.
