D-D – HOB SMART ATO NANO

Smart ATO Nano
Smart hang on automatic top up unit designed for small or nano aquariums with a dual safety sensor and diaphragm pump that can draw water from a reservoir next to a sump or from below in the aquarium cabinet.

A strong diaphragm pump and a dual optical sensor are combined in one compact hang on unit so there is no pump to fit in the reservoir, keeping everything neat and tidy.
