Thanks for the good info, Matt! Your findings on the recirculating are interesting. Recirculating sounds good in theory, but I can't say I have read any strong evidence that supports it. The fact that the cream of the crop BubbleKing skimmers are not recirculating makes me wonder as well. What you said about the aquabee reafirms my interest in going with something besides a sedra powered skimmer. I'd like to go with the H&S A200, but it is a big price drop to the next size down A150. I just realized I'm focused on the recirc skimmers, H&S has an in-sump equivalent to the A200 that is closer to my price range, but it is also 6" shorter. :wacko Thanks for the build offer, I've heard your stuff is great.
