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