A Smart and Silent Auto Top Off System

  • Smart ATO System with Alerts and Alarms
  • Silent Operation
  • Easy DIN Rail Mounting


Dosing pump ATO is a smart solution from Reef Factory designed for automatically topping up evaporated water in the aquarium. This incredibly precise tool is the result of combining an ultra-accurate pump with liquid level sensors. The Dosing pump ATO detects a drop in water level and automatically replenishes it, helping to maintain the desired salinity and stable parameters.

Thanks to precise data, monitoring the amount of added water to the system is very easy. The Smart Reef application allows you to set an alarm that informs you about the remaining water in the ATO reservoir. Furthermore, unlike traditional pumps used in automatic top-offs, Reef Factory's solution is ultra-quiet, thanks to the use of a dosing pump instead of an impeller style pump.

The Float Switches

Dosing pump ATO is equipped with reliable and trouble-free float switches. The lower float switch activates or deactivates the water top off, while the upper float switch will alert you in case of excessively high water levels, effectively acting as a redundant failsafe.
