anybody not running a skimmer on a large (300+) ESTABLISHED reef tank?

i have a 150 gal refuge with DSB. I have a very diverse population of organisms- cukes, stars, snails, worms.

I think I've seen a 220 or so gallon tank without a skimmer. The guy is German I think.

I do not have one on my 375 but it was just upgraded from a skimmerless 180 a few months ago so it is not much to look at yet.
