Refugiums: Yay or Nay?

[spedly]

I don't really have a reason for a refugium. I guess what's driving it more than anything is, "hey, I have a section in my sump for a refugium. maybe I should put something in there."

I like the sounds of "nutrient export" but I'm not sure if the section is big enough to have much of an impact. It's a 12.5"x14.5" section on a 150g display. Moreover that's probably not big enough to grow a sufficient amount of critters to feed a feed a mandarin.

I think I'm answering my own question as to whether or not I should get one going.
