In stock

- +

The HYDROS DC CO2 Solenoid Valve is the ideal solution for controlling the CO2 flow on your calcium reactor through your HYDROS controller. This multi-purpose accessory gives you the ability to regulate CO2 or air flow with plug-and-play simplicity. The HYDROS DC CO2 Solenoid Valve is electronically controlled and plugs into a Drive Port on the Control 2 and Control 4 where it can be monitored and controlled via the HYDROS app. There is no separate power supply required for a clean and simple installation.


The HYDROS DC CO2 Solenoid Valve works in conjunction with a HYDROS aquarium controller and when paired with a pH probe through the HYDROs controller, works seamlessly to maintain the proper pH range inside of a calcium reactor. You'll be able to control the on/off state of the CO2 solenoid attached to the regulator with the HYDROS app. You can configure your controller to automatically turn the solenoid valve on at high pH or close the solenoid valve at low pH to effectively dissolve your calcium reactor media and replenish calcium and other elements in your aquarium water.
