sunken ship

I have an 18g reef tank and the only water flow I have is from my penguin 170 filter. I am thinking of adding a powerhead. What would you guys suggest for a small tank like mine??? If you want to see any pictures of the set-up i have right now go check the photography forum and look for my name.

I'd put a maxijet 400 in there. Don't go with a mini maxijet though, they don't stick well and don't create enough current.
