HYDROS Control X4 Starter Pack

The HYDROS Control X4 Starter Pack by CoralVue is a complete, do-everything aquarium controller kit built around the flagship Control X4. One X4 monitors temperature, pH, ORP, and water level while controlling pumps, timers, and sensors — and this pack bundles the probe, sensor, and WiFi power strip you need to run it all from the free HYDROS app. Ideal for larger or more advanced saltwater, freshwater, and pond systems.

What's included

What you can do out of the box

Frequently asked questions

Why choose the X4 pack? It's the most capable single-controller kit — one X4 covers temperature, pH, ORP, and water level plus Drive Ports and 0–10V control, with no add-on modules needed.

Want more AC outlets? The X4 Pro Pack adds the eight-outlet XP8 controller and a Command Bus cable.
