RE: nano skimmers
mike,
that model is specifically designed to go into nano-cubes (jbj specifically but I am sure it would fit in most of them.) and when you think about it, those overflow boxes on those nano-cubes are the same thing as your talking about, except this skimmer sits IN it.
"Maybe in order to understand mankind, we have to look at the word itself: "Mankind". Basically, it's made up of two separate words - "mank" and "ind". What do these words mean ? It's a mystery, and that's why so is mankind." ~ Jack Handey
