Hydros Blenny Aquarium Controller and Micro Dosing Pumps
The HYDROS Blenny features four micro-liquid dosing pumps that work independently to accurately dose liquid supplements, including two-part and trace elements for maintaining a healthy aquarium.
This controller is ideal for both saltwater and freshwater aquariums, and it can be used independently or seamlessly integrated with other HYDROS devices. The Blenny is capable of sending alerts and notifications, and when paired with the HYDROS XP8, it can also control outlets for lights, pumps, feeders, and other aquarium accessories. All HYDROS products are meticulously engineered, assembled, and supported in the USA.

There is no complicated programming language to learn. If you can operate a smartphone, you can be the operator of a smart aquarium—tap, drag, press, or flick to adjust settings using intuitive icons and simple menus. Schedule each component in your aquarium life support system to run at a specific time, frequency, or intensity. You can also use real-time data and easily configure more complex actions.
HYDROS devices look like industrial controllers because they are built to function in the harsh environment of a marine aquarium. The IP65-rated HYDROS enclosure and aircraft-style connectors ensure long-term reliability in the face of splashes and corrosive salt spray.


The Command bus communicates with other HYDROS devices for the ultimate failsafe and can also power other Control devices.
The Drive Ports provide switched 12V DC power for running small HYDROS aquarium devices. The Control continuously monitors the exact current supplied by each port, so you will be immediately notified if a motor or pump quits drawing current or draws too much.
Each drive port can handle up to 1.5A, and the entire device can handle up to 3A in total.
