I'd have to agree with the above post on the SeaClone. JMHO. I think, for what they are, they work pretty well. They are nowhere near the equal of the Berlin or Aqua C of course, but they're a lot cheaper also. I added one to my puffer tank and almost immediately saw a huge increase in water clarity and a drop in algae growth. If you have room in the wet/dry, you can run...should run...the skimmer in there. Aqua C makes an in sump model called the Urchin that you might want to look at.
