Refugium

[adamRS80]

I'm thinking about getting a CPR style hang-on refugium for my tank. Is anybody using one of these? What do you think about it? I'd probably get a 50/50 PC light for it and keep some marco algae and frags while I'm trying to find something to do with them. I really just want to know if it's worth it.

I have two of them. Once your macro algae start to grow, you won't really have much rooms for frags. Some SPS can't tolerate macro algae close to them.
