If it's the one I'm thinking of (with the air pump & air stone), I'd recommend against it. The air stone requires regular replacement, and as the airstone depletes, you're constantly making adjustments to keep it skimming properly. If you're looking at putting the skimmer directly into the back corner of the tank, I'd maybe go with something like a small Tunze 9002 or Hydor slim-skim, or go with a BakPak HOB skimmer.
