The HYDROS Control XS by CoralVue is a compact, sensor-focused aquarium controller. Despite its small size, it handles the core jobs of a smart tank: it monitors temperature, senses leaks, controls equipment through HYDROS devices, and sends alerts. It's an ideal standalone controller for small-to-midsize saltwater or freshwater aquariums — and it drops easily into a larger HYDROS network.

Frequently asked questions
Does the Control XS switch power outlets directly? The XS is sensor-focused — it controls power through HYDROS WiFi devices (like the WiFi Power Strip or Smart Plug) or another HYDROS controller such as the XP8.
How many sensors can I add? Up to four at once, one per universal Sense Port, added in seconds with no extra modules.
XS or X2? Choose the XS when your priority is sensing and monitoring with four Sense Ports; choose the X2 if you also want built-in Drive Ports to power small 12V devices.
Want everything to get started? The Control XS Starter Pack bundles the unit with a power supply, temperature sensor, and 4-Outlet WiFi Power Strip.
