HYDROS Float Switch with Magnetic Mount: Smart, Hassle-Free Water Level Monitoring

The HYDROS Float Switch with Magnetic Mount makes water level monitoring one less thing to worry about. Whether you are topping off RO/DI reservoirs or automating skimmer shutoffs, this little sensor handles the job like a pro—no overthinking, no overflowing.

Why the HYDROS Float Switch Belongs in Every Tank Setup

From saltwater systems to freshwater frag tanks, the HYDROS Float Switch keeps your water levels dialed in. If you’ve ever walked into your fish room and found your ATO dumping like it’s the Niagara Falls, this switch is your new friend.

Key Benefits of the HYDROS Float Switch:

• Auto Top-Off Support: Helps refill tanks without overfilling

• Alarm Triggering: Alerts you when levels go too high or too low

• Reservoir Monitoring: Prevents RO/DI containers from running dry

• Skimmer Control: Automatically powers down skimmers if sump levels rise

And yes, it works for both reefers and freshwater folks—no gatekeeping here.

HYDROS Float Switch - Built to Last in Saltwater and Freshwater Systems

Let’s be honest, saltwater gear can be picky. But the HYDROS Float Switch doesn’t discriminate—it works great across both tank types. So whether you’re chasing SPS color or just trying to keep your goldfish from beaching itself, you’re covered.

Installation is as easy as feeding your fish (and probably less messy). The strong magnetic mount holds tight to surfaces up to 2cm thick—no drilling, no fuss, no lost tools in the sump.
