The HYDROS Start is the perfect first aquarium controller, expertly designed to combine a variety of essential features into a single, user-friendly device. This all-in-one solution allows you to effortlessly manage a wide range of aquarium functions, making it an ideal choice for both beginners and experienced aquarists alike.
It is easy to use and features key functions such as temperature monitoring and power control for up to four devices. You can expand its capabilities with optional accessories that detect leaks, monitor water levels, and manage 12V HYDROS equipment. It works with the HYDROS App for simple system management and fits a variety of setups, including saltwater tanks, freshwater tanks, and ponds. It can be used on its own or as part of a larger HYDROS system as your needs grow.
All HYDROS controllers 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.

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.
