HYDROS Duet Aquarium Controller w/ Dosing Pumps

HYDROS Duet – Dual Continuous-Duty Dosing Pump & Aquarium Controller

The HYDROS Duet combines two powerful continuous-duty stepper motor dosing pumps with intelligent aquarium control. Available at Reef Supplies Canada, it's designed for demanding freshwater and saltwater applications, including automatic water changes, calcium reactor effluent control, kalkwasser dosing, sulfur reactors, and liquid food delivery.

Each reversible pump operates from 0.1 to 600 ml/min, providing precise flow control for both low-volume dosing and high-volume water changes.

Managed through the HYDROS cloud-based app, the Duet offers remote monitoring, customizable schedules, push notifications, and automated alerts without programming. It operates independently or integrates with other HYDROS controllers for expanded automation.

Its IP65-rated enclosure, aircraft-style connectors, and dual-core 32-bit processor provide durability in demanding aquarium environments. Four Sense Ports, one 12V Drive Port, and two Command Bus connections support additional sensors and accessories.

Key Features

• Dual Continuous-Duty Pumps: Two reversible stepper motor pumps delivering 0.1–600 ml/min each.

• Automatic Water Changes: Reversible operation simplifies drain-and-fill configurations.

• Smart App Control: Remote monitoring, scheduling, push notifications, and custom alerts through the HYDROS app.

• Easy Automation: Intuitive tap-and-drag setup without programming.

• 4 Sense Ports: Compatible with temperature, optical and capacitive water level, flow, leak, and other HYDROS sensors.

• 1 Drive Port: Switched 12V DC output for compatible pumps, fans, solenoids, and accessories.

• 2 Command Bus Ports: Enable communication and power sharing between HYDROS devices.

• Durable Construction: IP65 splash-resistant housing with aircraft-style connectors.

• Expandable System: Standalone operation or integration with additional HYDROS equipment.

• Serviceable Components: Pharmed pump tubing rated for approximately 1,000 operating hours.

Ideal Applications

• Automatic Water Changes: Schedule precise drain-and-fill cycles using continuous-duty pumps.

• Reactor Control: Regulate calcium reactor effluent, kalkwasser delivery, and sulfur reactor flow.

• Supplement Dosing: Automate liquid foods, amino acids, and aquarium additives.

• Sensor-Based Automation: Integrate level sensors and leak detectors for additional protection.

• HYDROS Expansion: Add dosing capabilities to an existing HYDROS aquarium control system.

Pro Tips from Reef Supplies Canada

• Expand Your Control: Pair the Duet with a HYDROS XP8, Smart Plug, Launch, Start, or WiFi Power Strip for outlet control. These accessories are sold separately.

• Maintain Pump Heads: Replace Pharmed tubing as needed, approximately every 1,000 operating hours. Tubing, rollers, and bushings are serviceable wear components.

• Calibrate Water Changes: Verify each pump's output and balance drain-and-fill volumes before enabling automatic schedules.

• Add Safety Sensors: Use compatible water level sensors to stop dosing when unexpected reservoir or sump levels are detected. Pump monitoring can also trigger alerts if current draw stops unexpectedly.
