Compact Aquarium Automation with Real Expansion Potential

The HYDROS Control X2 is a compact yet powerful aquarium controller designed for hobbyists looking to automate and monitor their aquarium while still leaving room to grow.

Unlike some entry-level aquarium controllers, the X2 includes both Sense Ports and Drive Ports, allowing you to monitor your aquarium and power compatible HYDROS accessories from the same device.

Perfect for:

• Reef aquariums
• Freshwater systems
• Nano tanks
• Fish-only systems
• Automatic feeding
• ATO systems
• Cooling fan automation
• Leak detection and monitoring

Learn the Ports – What Do They Actually Do?

One of the biggest learning curves with aquarium controllers is understanding the ports and what they are used for. HYDROS keeps things simple by organizing ports by function.

Sense Ports (Green) – Monitoring Inputs

The X2 includes 2 Sense Ports.

Sense Ports are used for devices that monitor or detect something happening in your aquarium.

Compatible devices include:

• Temperature sensors
• Optical water level sensors
• Leak detectors
• Float switches
• Flow sensors

These ports allow the controller to “sense” conditions in your aquarium and automate actions through the HYDROS app.

Example:

If your sump water level drops, the X2 can trigger an ATO pump automatically.

Drive Ports (Orange) – Powered Outputs

The X2 includes 2 Drive Ports.

Drive Ports provide controllable 12V DC power to compatible HYDROS accessories.

Common Drive Port accessories include:

• HYDROS Automatic Feeder
• Cooling fans
• ATO pumps
• Solenoids
• Cabinet lighting
• Small utility pumps

These ports allow the controller to automatically power devices on and off based on schedules, water level, feeding modes, temperature, and more.

Important Compatibility Note

The HYDROS Automatic Feeder requires a controller with an available Drive Port.
The X2 supports the feeder directly.
The X3 does not include Drive Ports.

Command Bus Ports (Blue) – System Expansion

The X2 includes 2 Command Bus Ports.

These ports allow HYDROS devices to communicate and expand into a larger automation ecosystem over time.

This means your controller system can grow with your aquarium instead of needing a full replacement later.
