Well, I took the plunge and bought a used 90 gallon reef setup at my local LFS. I think I got a good deal....tank, stand, sump, skimmer, light etc for $650. The worker said it was the owner's old tank so I would think it's all top of the line stuff. Looked like it anyway. Just got it home and in the house, going to take stock of what I've got in a little while.
