I was just looking for a skimmer for my 10G. I WAS looking into the Fission, but SCSI talked me out of it in one sentence. I need a smaller one (u know...because its a 10 Gallon), but I need the quietest one I can find. My 10 Gallon is set up in an office I share with a couple of others and I need it to be quiet, one of the guys has already expressed his hatred for the sound of bubbles, and I have to agree with him.
