HYDROS Leak Detection Sensor

HYDROS Leak Detection Sensor - Protect Your Aquarium Setup

The HYDROS Leak Detection Sensor is the silent guardian your aquarium didn’t know it needed—until water hits the floor. Whether it’s a slow drip or a full-on flood, this smart sensor helps stop disasters before they start. It plugs right into your HYDROS controller and starts watching like a hawk. Well, a waterproof, low-profile, extremely precise hawk.

Key Features of the HYDROS Leak Detection Sensor

This isn’t just a piece of gear—it’s peace of mind in a puck-sized package.

• Helps stop damage before it starts by sending real-time alerts

• Ideal for spotting leaks around sumps, ATO containers, skimmers, and plumbing

Plug-and-Play Simplicity

• Connects straight into any HYDROS Sense Port—no power brick, no extra fuss

• Sets up in seconds, whether under your tank stand or next to a bucket of salt mix

Fully Customizable Alerts Through the HYDROS App

This sensor does more than beep and blink—it takes action.

Program the HYDROS app to:

• Flash controller lights for visual warnings

• Shut down return pumps or skimmers before flooding happens

• Send push alerts to your phone for real-time status updates

You can even trigger multiple actions based on sensor readings, turning your reef setup into a full-on smart aquarium.
