I read it on RC in a thread that was pretty cool but it was sometime back.
the thing about skimmers also is that they supply copius amounts of o2 and that in itself is why I prefer them over a scrubber. also, if something dies while your gone at least the skimmer would react a lot faster than a scrubber. so just those 2 benefits to me out gun a scrubber. I have a refugium as well. but a skimmer is a piece of mind. IMO
