should I

[stagofdoom]

I have a 24 gallon nano and I was wondering if I should get this.
Water Pumps & Wavemakers: Hydor Koralia Water Circulation Pumps

ive got a little powerhead at the top and it doesnt move around that much.

I think either the Nano powerhead or the Koralia 1 would be good for your tank.

I would go with atleast one 1koralia if not 2 depending on what kind of flow you are looking for. I have 2 number 3s and 2 maxijet mods in my 90. I really like the koralia, they are quite and move alot of water.

Good quiet circulation pumps and the magnets make it so much better than suction cups.I would go with two of the nanos or one K1.
