Hydros Control X2 The Hydros Control X2 is a compact general-purpose HYDROS aquarium controller designed for freshwater and saltwater systems that need reliable monitoring, basic automation, app-based alerts, and expandable control without moving into a larger controller right away. With two Sense Ports, two 12V Drive Ports, two Command Bus ports, and support for compatible HYDROS WiFi devices, the Control X2 is a strong starting point for aquarium owners who want to monitor temperature, detect leaks, automate simple equipment, and build a system that can grow over time. HYDROS Control X2 Aquarium Controller Overview The Control X2 is built for aquariums where dependable monitoring and practical automation are more important than having every advanced port in one controller. It can be used as the main controller on a smaller reef, freshwater planted tank, quarantine system, utility system, or basic fish-only aquarium, and it can also join other HYDROS devices as part of a larger Collective. This makes it useful both as an entry-level controller and as an expansion device for adding extra Drive Ports and Sense Ports in another cabinet, sump area, or equipment location. For hobbyists looking to prevent common aquarium problems, the Control X2 offers a practical mix of sensing and direct 12V accessory control. It can be configured for temperature monitoring, leak detection, water level sensing, flow monitoring, ATO pump control, cooling fan control, cabinet lighting, solenoid operation, alerts, and smart outlet control when paired with compatible HYDROS WiFi outlets or power strips. The HYDROS app keeps setup approachable with icon-based controls, rules, schedules, and notifications instead of traditional controller programming. HYDROS Control X2 Monitoring and Automation Features Two universal Sense Ports: The Control X2 includes two Sense Ports for connecting compatible HYDROS sensors such as temperature probes, optical level sensors, leak detectors, flow sensors, magnetic switches, and push-button switches. These inputs let the controller watch the aquarium and respond to changing conditions before small problems become major failures. Two 12V Drive Ports: The Drive Ports provide switched 12V DC power for small HYDROS-compatible accessories. They are useful for equipment such as ATO pumps, cooling fans, cabinet LEDs, and solenoids, giving the Control X2 direct low-voltage output control without needing a separate AC outlet for every small device. Current-monitored drive output: Each Drive Port can monitor current draw, allowing the system to alert the user if a connected motor or pump stops drawing current or draws too much. This is especially useful for ATO pumps, small utility pumps, and other devices where silent failure can create real aquarium risk. Two Command Bus ports: The Command Bus provides power and communication between HYDROS devices, allowing the Control X2 to become part of a larger HYDROS system. This wired communication path supports a more dependable control network than relying on a single central controller alone. Control of compatible WiFi devices: The HYDROS app allows the Control X2 to manage compatible HYDROS WiFi power strips and smart outlets. This lets users switch larger AC-powered aquarium equipment such as heaters, return pumps, lights, skimmers, algae scrubbers, UV sterilizers, and feeders based on schedules, manual commands, or sensor-based rules. Standalone or Collective operation: The Control X2 can run on its own or join a HYDROS Collective with other HYDROS controllers. In a Collective, inputs and outputs can work together as one larger system, making the Control X2 useful for staged upgrades and distributed aquarium control. Local and cloud-based access: HYDROS supports local WiFi control and remote cloud access through the app, giving users a way to check system status, receive alerts, and adjust compatible equipment when they are away from the aquarium. Aquarium-ready enclosure: The IP65-rated enclosure is designed for dusty and splash-prone environments around aquarium stands and sumps. It is splash resistant and dust protected, but it should still be mounted properly and protected from direct water exposure. Internal health monitoring: The controller reports internal operating information such as voltage, current, CPU status, and internal temperature, giving the system additional awareness beyond the external aquarium sensors. Compact installation footprint: The smaller body makes the Control X2 easy to mount inside cabinets, near sumps, beside quarantine tanks, or in utility areas where a larger controller would be harder to place cleanly. Hydros Control X2 Specifications Product type: General-purpose aquarium controller UPC: 850009641168 J&L SKU: HD-C2 Sense Ports: 2 12V Drive Ports: 2 Command Bus ports: 2 HYDROS WiFi device control: Up to 8 compatible HYDROS WiFi devices Drive Port capacity: Up to 1A per Drive Port and up to 1.5A total for the device Processor: Dual-core 32-bit processor Dimensions: 5" L x 2.7" W x 1.9" H WiFi compatibility: 2.4GHz only Enclosure rating: IP65 dust and splash protection; not waterproof Mounting bracket: Yes Warranty: 1-year limited warranty Application: Freshwater and saltwater aquarium monitoring, low-voltage accessory control, alerts, and HYDROS ecosystem expansion Compatibility and Application Notes The Control X2 is best suited for systems that need two sensor inputs and two low-voltage control outputs. It is a good fit for ATO safety, leak detection, temperature monitoring, small pump control, cooling fan control, cabinet lighting, and basic smart outlet automation. It does not include built-in pH, ORP, or salinity probe ports, so those applications require a different HYDROS controller or an added HYDROS device with the required probe input. Setting Up Your HYDROS Control X2 Download the HYDROS app, register the controller, connect it to a 2.4GHz WiFi network, and update the firmware if prompted before configuring inputs or outputs. Mount the controller permanently in an elevated location such as a cabinet wall or side panel, avoid placing it on the floor, and use proper drip loops on all cables. Once online, add sensors, configure Drive Port outputs, create alerts, and add the Control X2 to a HYDROS Collective if it will be used with other HYDROS controllers.
