Thanks all. I took me a whole summer to build the stupid thing!!
Jamie, any idea where I can get some nice frags to seed it with?
Christy, what's this talk about a sump? These skimmers go in sumps? Hmm, that'll look better than in tank, I guess. (Sump is still being re-baffled to suit my needs, it's a 33g, so not much room.)
