HYDROS Minnow: Smart Aquarium Controller with Sensor Integration and Dual Dosing
The HYDROS Minnow Aquarium Controller is small but mighty—kind of like the Swiss Army knife of the dosing world. Whether you're keeping a nano reef, a freshwater planted tank, or even a koi pond in the backyard, the Minnow makes dosing smarter, cleaner, and way less stressful.
With two built-in micro dosing pumps and four Sense Ports, this controller handles your supplements and sensors like a pro. And yes, it fits in the palm of your hand—pretty impressive for something that could practically run your tank.
Precision Dosing That Keeps Things Balanced
Those two dosing pumps aren’t just for show—they work independently to deliver precise amounts of liquid supplements.
Highlights:
-
Doses two separate liquids like two-part calcium and alkalinity
-
Ideal for trace elements, kalkwasser, or liquid foods
-
Maintains consistent dosing schedules without babysitting
Four Sense Ports = Real-Time Monitoring Power
The HYDROS Minnow doesn’t just dose—it listens to your tank like it’s got ears in the water.
Sensor Compatibility:

This kind of flexibility means your tank runs smarter, and you can sleep a little easier.

Tim Brown –
Definitely a good addition to any tank. My only qualm isn’t with the controller so much as with the app control of the dosers. Both are capable of running forward and backward which is awesome for auto dosing things like refrigerated or live food, but the app won’t let you run a forward then backward schedule – pick one only. With that said, I can manually dose, then switch to reverse and dose again to purge the lines, just a little annoyance more than anything.
