I have a Prizm skimmer on my 16 gal at home (it's on the sump) and it does the trick. I looked at that nano skimmer you guys are talking about. They have one at AI here in Edmonton on a 10 gal (or so). Didn't look like it could do much. For my 2.5 gal at work I am building a skimmer out of a 2L pop bottle. It's a pretty straight forward venturi skimmer. It'll be cheap like borscht to make
