Overview

Controller Designed for Automatic Water Changes

The HYDROS Duet is a professional-grade aquarium controller and monitoring system built around two super-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

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)
Capacitive non-contact liquid level sensors
Rope leak detectors
Point leak detectors
Flow rate sensors
Magnetic switches
Push-button switches

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.

Super-Duty Liquid Doser

The HYDROS Duet features two (2) super-duty liquid dosing pumps that are capable of performing automatic water changes to fresh or marine aquariums.

The Duet Doser Features:

Quiet Operation
Robust Stepper Motors
For Continuous Use
Can Run in Reverse
Includes Barbed Fittings
Easy to Service
