I wish that Evan would give a seminar on refugiums - a 75 for a 75. That is the coolest system. The 'fuge in this case is a nice tank in its own right, not a green mess as we sometimes see. You have 2 different microcosms side-by-side.
So that would mean you could have a 20 for your fuge, with the benefits Kari mentions. (Guess I need another 50 then...)
