A single controller trying to monitor temperature, pH, ORP, and water level while also automating every piece of equipment in the tank is exactly the job the flagship of a controller lineup should be built for. The HYDROS Control X4 by CoralVue is CoralVue's all-in-one automation hub, and the flagship of the entire HYDROS system.
What Makes the X4 the Flagship
Where the X2 covers the basics and the X3 adds water chemistry monitoring, the X4 combines temperature, pH, ORP, and water level monitoring with full equipment automation in a single unit — the most capable single-controller option in the HYDROS lineup before stepping up to a multi-device setup like the Kraken.
What the Control X4 Offers
- Comprehensive monitoring across temperature, pH, ORP, and water level from one device.
- Full equipment automation through the same HYDROS app used across the whole ecosystem.
- Expandable via accessories — dosing pumps, additional sensors, and power strips all integrate with the X4 as your system grows.
Choosing a Package
- Control X4 — standalone unit for keepers building out their own accessory set.
- X4 Starter Pack — a complete, do-everything kit built around the X4.
- X4 Pro Pack — the top-tier HYDROS bundle, pairing the X4 with the eight-outlet Control XP8 for maximum automation from day one.
