Hydros Control X3-S (Controller Only): Smarter Aquarium Automation in a Compact, Rugged Design

The Hydros Control X3-S (Controller Only) is not just another aquarium controller — it’s your tank’s new command center. Built like it belongs in a NASA control room (minus the space suits), this compact powerhouse handles sensors, probes, pumps, and even sends alerts before disaster strikes. Whether you’re a reef tank veteran or just starting out, the X3-S gives you the brains of an automation system without the extra fluff.

Smart Aquarium Automation of the Hydros Control X3-S Without the Fuss

No more "Where’s that outlet?" moments. No more spaghetti cable nightmares. Just streamlined, smart control.

The Hydros X3-S connects to two sensor devices and a probe port, giving you essential real-time data.

It supports:

• Temperature sensors

• Optical and capacitive water level sensors

• pH or ORP probes

• Rope and point leak detectors

• Flow sensors and magnetic switches

You can also:

• Set up automated alerts and tank failsafes

• Control outlets for lights, pumps, and feeders

• Use it standalone or expand it with other HYDROS gear

• Manage everything through the HYDROS app — from anywhere

Hydros Control X3-S: Built for Brutal Reef Environments (Seriously)

If your sump area looks like a splash zone at SeaWorld, no worries — the X3-S can take it.

Rugged Features That Matter:

• IP65 Rated – Resists water spray and salt creep like a champ

• Passively Cooled – No noisy fans, no overheating drama

• Industrial Connectors – Like tiny seatbelts for your cables

• Internal Monitoring – It checks its own vitals so you don’t have to

Translation: This thing is tougher than your cousin’s overcooked Thanksgiving turkey.

Plug-and-Play with a Brain

Every HYDROS device comes with its own processor. That means no central “hub” to crash and ruin your day.

Here’s what that gives you:

• Faster decision-making (think milliseconds, not minutes)

• Scheduling built into each device

• Control redundancy (no single point of failure)

• Seamless communication across the Command Bus system

You could connect it to a complex tank setup or keep it simple. Either way, it works — reliably and quietly.

What’s Included in the Hydros Control X3-S package?

This version is controller-only, perfect for expanding your system or replacing an older unit.

Key Connections:

• 2 Sense Ports – Plug in sensors for temp, leaks, water level, and more

• 1 Probe Port – Supports either a pH or ORP probe

• 2 Command Bus Ports – Share power and data with other HYDROS devices

That probe port? It's not your everyday pH jack. It uses digital galvanic isolation to prevent electrical noise — keeping your readings rock-solid and accurate.
