The Bermuda looks like a great design, but I haven't heard of them. How did you happen across it? I have always heard that Tunze is terrific. I use Octopus myself so I don't have experience with either of these two.
made a post on reef central asking which HO skimmer I should get. They said the Bermuda and the unze 9010 were my only choices, everything else is mediocre to garbage.
