Cliff I have all sorts of possiblities. I was only pointing out that the Octopus skimmers are very large for their rated size. to me, IMO, that is a sign of not being very efficient. That was my only point. As in, I'd rather have a more efficient, more compact skimmer under my stand. Nothing more than that. It's not my problem since I won't be buying one. I just wanted to point out that they seemed ridiculously large and that could be a major deciding factor for this buyer. I was only making the comparison to my tank to make a point that indeed size can be a factor.
