The HYDROS Control X2 by CoralVue is an affordable, general-purpose aquarium controller that monitors your tank and automates your equipment — no coding required. It tracks temperature, leaks, and flow, powers small devices, and switches outlets on a schedule or in response to real-time conditions. Use it as a standalone controller for a saltwater reef or freshwater planted tank, or link it with other HYDROS devices to build a larger system. Key features Two Sense Ports — universal inputs for temperature sensors, water-level sensors, leak detectors, and more. Two Drive Ports — supply switched 12V DC power to small devices and monitor current for failures. Two Command Bus ports — power and link multiple HYDROS controllers into one failsafe network. Controls up to eight HYDROS WiFi devices — 4-Outlet WiFi Power Strips and Smart Plugs for pumps, heaters, lights, skimmers, UV, and more. App-based automation — schedule an auto top-off, temperature-controlled heater, or lighting timer in a few taps. Specifications Dimensions (L×W×H): 5″ × 2.7″ × 1.9″ Processor: fast dual-core 32-bit — each device makes control decisions on its own Health monitoring: reports internal voltages, currents, CPU status, and temperature Build: splash-proof and dust-resistant industrial enclosure Frequently asked questions What's the difference between the Control X2 and X3? The X2 has two Sense Ports and two Drive Ports. The X3 swaps in a dedicated Probe Port so it can also monitor pH and ORP. Can the Control X2 turn my equipment on and off? Yes. It controls up to eight HYDROS WiFi devices (like the WiFi Power Strip or Smart Plug), and its Drive Ports directly power small 12V devices. Does it work on freshwater tanks? Yes — it's built for both saltwater aquariums and freshwater planted tanks. Stepping up in capability? Compare the Control X3 and Control X4. Prefer a bundle? Grab the Control X2 Starter Pack.
