Now that I have added some more rock to my little 20 gal invert tank, the HOB filter does not seem to be moving enough water. I have been reading and thinking about adding a powerhead to move some more water around and was just wondering what popular oppinion would say about a simple affordable unit.

i would say a maxijet 600 or koralia nano would be perfect

I have 2 of the koralia nanos very quiet and they do not take up much space in your tank

Those Koralia nano's don't move that much water IMO. Go bigger. The inverts will thank you for it.
I have a Koralia #1 and two #2's in my 20 gallon right now and wish I had gone bigger. :)

Ditto! I got one of the nanos and they just do not compare to the big brothers. I would go with the Koralia #1

I used a Koralia #3 in my 10g QT and loved it.. it would probably be great in a 20g :lol2:

just my 2 pennies...

I would go with 2x Koralia #2.

Thanks for the info, looks like I will be adding a Koralia to my shopping list soon.
