CoralVue Hydros DC Micro Pump

With a HYDROS DC Micro Pump and a HYDROS Optical Water Level Sensor (or Float Sensor), you can use the HYDROS Control X2 and Control X4as an auto top-off (ATO) system. Just plug the pump into a Drive Port and the optical water level sensor into a Sense Port on Control 2 or Control 4 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.
