With a HYDROS DC Micro Pump and a HYDROS Optical Water Level Sensor (or Float Sensor), you can use a HYDROS Control as an auto top-off (ATO) system. Just plug the pump into a Drive Port and the water level sensor into a HYDROS Control and adjust your settings in the HYDROS app. In addition, you can add additional HYDROS optical water level and/or mechanical float sensors to your ATO configuration for redundancy and set high/low points.
The HYDROS DC Micro Pump is powerful despite its small size. The pump measures 1.6” L x 1.062” W x 1.45” H. The pump has a maximum head pressure of 8’. The flow rate of the pump is 74 gallons per hour. This 12V brushless pump draws a maximum of 4.5W and has an average life expectancy of 30,000 hours (over three years). When connected to a Drive Port on a HYDROS Control and the controller will supply power to the pump, so no additional cords or power bricks are required for operation. Using a HYDROS aquarium controller for your auto top-off system is a reliable solution and helps clear wire clutter in and around your aquarium.
