kip- that's a great use for the fuge that i have yet to hear! no corals yet but someday i'll use that tip.
i love my fuge (even though its a rubbermaid and hard to see anything inside it). i've had my tank up for about 4 months now and, since its cycled after the 1st month, trates have been zero! i do WCs anyway. but i love the zero trates. i have pods, LR, DSB, and a whole lot of chaeto in it.
