So, I only have a 20 gallon tank...would 1 powerhead be enough? The people at my LFS said that my filter wouldn't be enough water motion. What do you guys think? Personally, I think a lil more motion in the water wouldn't be too bad...and plus I know it's good to keep the live rock clean. Also, it wouldn't be anything too powerful...wouldn't want to blow the fish away lol.

I am thinking more like 2-3 for a 30 gallon. I have a 29 and started out with 2, and added a 3rd just a few days ago.
