I've been looking around for a good deal on a pump for my skimmer, but the other day I remembered I have a spare penguin 1140 powerhead. I rigged it to fit when I was bored, and it seems to be working. It may be a little to strong (at 300gph), but it's skimming. I'm not really satisfied w/ the performance, so I'll probably keep looking, but I did not think it would actually work... Just felt like sharing.
