HYDROS Sole Controller for Continuous Liquid Dosing in Reef Aquariums

   

Let’s be real—running a reef or planted tank takes effort. You’re juggling water changes, dosing schedules, and equipment checks while trying not to spill kalkwasser on your phone. The HYDROS Sole is here to change that. Designed to handle nonstop liquid dosing and smart aquarium automation, it gives you back time while keeping your system in check.

Whether you’re adding trace elements, topping off your ATO, or dialing in effluent from a calcium reactor, this compact controller can handle it—quietly, consistently, and without breaking a sweat.

 

The HYDROS Sole - Built for Hobbyists Who Want Control Without the Headaches

The HYDROS Sole is no one-trick pony. It works just as well on a standalone setup as it does in a fully connected HYDROS system. Saltwater or freshwater, beginner or seasoned pro—it scales to your tank's needs.

What It Can Do:

  • Doses continuously or at scheduled intervals

  • Works with calcium reactors, liquid foods, kalkwasser, and sulfur reactors

  • Controls pumps, heaters, and lights when linked to a HYDROS XP8 or WiFi power strip

  • Sends custom alerts when things go sideways

This isn’t just another pump. It’s the tank assistant you didn’t know you needed.

HYDROS Sole Dimensions

Here’s What You Get in the HYDROS Sole Box:

  • HYDROS Sole Controller

  • Power Adapter

  • Calibration Beaker (because accuracy matters)

 

Specs That Actually Matter to Hobbyists:

  • Size: 6" L x 3.6" W x 4.125" H

  • Tubing Fit: ¼ inch (3x5mm push-fit)

  • Dosing Speed: From a trickle (0.1 mL/min) to a steady pour (300 mL/min)

Smarter by Design—Connected When You Want It

Need to change your settings from the couch or while you're out grabbing salt mix? No problem. The HYDROS app lets you control everything from your phone. It’s intuitive, quick, and doesn’t require a tech degree.

Smart Highlights:

  • Dual-core processor for real-time decisions

  • WiFi-based app control for iOS and Android

  • Built-in alerts for voltage issues, CPU usage, or system errors

  • Internal diagnostics keep you informed

  • Command Bus lets it talk to other HYDROS gear

HYDROS Sole Smartphone App

Set It Up in Minutes, Not Hours

No coding. No complicated menus. Just a clean, user-friendly app that lets you drag, drop, schedule, and automate whatever your aquarium needs. You can tell this was designed by folks who actually own tanks.

Built to Handle Marine Mayhem

We all know saltwater isn’t kind to electronics. That’s why the HYDROS Sole is wrapped in a splash-proof shell, with aircraft-style connectors and a design that laughs in the face of humidity, salt creep, and accidental splashes.

Hydros Sole - Quiet, Reversible, Reliable Dosing Pump

Some pumps sound like a blender and others barely work after a few weeks. This one hits the sweet spot:

  • Whisper-quiet operation

  • Reversible motor (yes, it can push and pull fluid)

  • Push-fit tubing makes cleaning easy

One App, Up to 8 Devices with the HYDROS Sole paired with the HYDROS App

Control up to eight WiFi outlets with a single tap. Whether it’s your UV sterilizer, your return pump, or your heater, you can manage it all from one place.

Note: Requires a HYDROS XP8 or WiFi Power Strip. Those are sold separately.

Covered Where It Counts

CoralVue includes a 1-year warranty on the HYDROS Sole. It covers any manufacturing or material defects—just make sure you’re the original owner and not trying to rewire it with duct tape and hope.

  *WiFi Power Strip or Control XP8 is required, sold separately
If you're serious about aquarium automation but don’t want to overcomplicate things, the HYDROS Sole hits that perfect middle ground. Smart. Durable. Dead simple to use.
