JBJ Nano ATO Auto Top-Off Advanced Kit

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

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.

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.
