I'm not new to saltwater, but I've been going about it cheaply and have paid the cost. I have a 110G with a fluval 407 that came with it used. I have Fish, inverts, and just polyp and mushroom corals. I'm ready to spend some money on a new 75G and want to go with a refugium and better lighting. The canister is a pain to keep cleaning. I know very little about refugiums and hookups. Is there a site or some books that may help me? I was looking at a Fiji-20 sump, and I understand I would have to have my tank drilled out for an overflow. Where can I have that done other than buying the whole system? Or am I still trying to get away to cheap?? Help!!! Thanks guys
