Works great and quiet!

I use this pump in my 29 gallon and 40 gallon tanks. I think the increased water flow helps the tanks stay cleaner (combination of sponge and ziss filters). It also seems to help reduce algae, and best of all, the fish love it! The rummy nose tetras and the dwarf neon rainbows especially love to get right in front of it and swim against the current. It's fun to watch them play!

Quiet, powerful, and gets the job done

I installed this on my 75g to improve flow since my Cascade 700 couldn't quite alleviate all the dead spots in the hardscape. Works beautifully. A couple of things to anyone considering/working with one of these:

- The external magnet is necessary to eliminate noise with this pump. It may seem loud if you are experimenting with position, but once fully mounted it is silent.
- When you're setting this pump up, turn it upward and shake lightly to dislodge any extra air trapped in the internals. This helps cut down on noise as well.
- Because the pump uses a suction cup and paired magnet, you can't really mount it through a 3D background. This made it tough to get exactly the orientation of flow that I wanted.
- The cord is a little short, for a large tank depending on position you might need some creative wiring to make a drip loop.

Good little pump

I use this in my 33 long to circulate my water. It isn’t too strong for my guppies, Tetras, or dwarf neons. I don’t leave it on 24/7 though, especially now that I have guppy fry.

Great little pump

Koralia nano circulation pump is a nice addition to my 30 gallon planted tank. Gives just the right amount of water movement.
