Description
Aquarium Controller Designed for Automatic Water Changes
The HYDROS Duet is a professional-grade aquarium controller and monitoring system built around two continuous-duty liquid dosing pumps, engineered for high-volume liquid management in both freshwater and saltwater aquariums. Designed for demanding applications like automatic water changes, calcium reactor effluent control, kalkwasser additions, liquid food dosing, and sulfur reactor feeding, the Duet delivers the precision and reliability that hobbyists and professionals depend on. It works seamlessly as a standalone controller or as part of a broader HYDROS ecosystem, and when paired with a HYDROS XP8, it unlocks full outlet control over lights, pumps, feeders, and other accessories. Real-time alerts and push notifications keep you connected to your aquarium around the clock.

What you can expect from your HYDROS Smart Device
*HYDROS WiFi Power Strip, Control XP8, or Smart Plug required, but not included with Duet
- Control your HYDROS device(s) from anywhere in the world using the technologically advanced HYDROS cloud-based app
- Ability to monitor and control your HYDROS device(s) locally through WiFi
- Connect up to eight WiFi devices, such as the HYDROS Smart Plug or the WiFi Power Strip
- A fast dual-core 32-bit processor that allows control decisions to be made within each device
- The user sets the alerts and notifications
- Internal health monitoring to report voltages, currents, CPU status, and the internal temperature of each device

4 - Sense Port
The Sense Port is a new concept in aquarium parameter measurement. HYDROS devices include several Sense Ports. A Sense Port is a generic input port that can accept data from numerous different types of sensors.
Sense Ports currently support:
- Temperature probes
- Optical level sensors (single and dual)
- Rope leak detectors
- Point leak detectors
- Flow rate sensors
1 - Drive Port
The Drive Port provides switched 12V DC power for running small lights, motors, pumps, fans, and other accessories. Each drive port can handle up to 1A, and the entire device can handle up to 1.5A total. The Control continuously monitors the exact current being supplied by each port, so if a motor or pump quits drawing current or draws too much, you will be immediately notified.
Accessories currently supported include:
- Auto Top-Off (ATO) pumps
- Diaphragm Pumps
- Air Pumps
- Cooling fans
- Cabinet LED lights
- Solenoids to control reverse osmosis systems
Quick & Easy Setup
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.
Splash Proof, Dust Proof, and Secure Connection
HYDROS devices look like industrial controllers because they are built to function in the harsh environment of a marine aquarium. The Robust HYDROS enclosure and aircraft-style connectors ensure long-term reliability in the face of splashes and corrosive salt spray.
Command Bus - 2 Available
The Command bus communicates with other HYDROS devices for the ultimate failsafe and can also power other Control devices.

The Duet Doser Features:
- Quiet Operation
- Robust Stepper Motors
- For Continuous Use
