HYDROS Control X3 Monitor Pack

The HYDROS Control X3 Monitor Pack by CoralVue is a monitoring-focused aquarium controller kit that watches temperature, pH/ORP, and leaks out of the box. Built around the Control X3, it's the ideal way to keep an eye on your tank's vital parameters and get instant alerts — and it upgrades to full outlet control anytime by adding a HYDROS WiFi Power Strip or Smart Plug.

Frequently asked questions

How is the Monitor Pack different from the Starter Pack? The Monitor Pack is built for monitoring — it includes a point leak sensor but no power strip. The X3 Starter Pack includes the 4-Outlet WiFi Power Strip so you can switch equipment right away.

Can I add outlet control later? Yes — add a HYDROS WiFi Power Strip or Smart Plug and the same system controls lights, pumps, feeders, and more.
