Ha... you're right down the road!! You've also got Monfort Aquariums down on Colerain Ave. not too far from you, Gerber's Saltwater Warehouse up here in Dayton (they're a bit overpriced, but knowledgeable). Coral Cove is up in Englewood.... small shop, but also knowledgeable people, and they're associated with a local forum.
Since you're just setting up, you won't be ready for corals yet, but there's a local frag swap going on Nov 3rd in Cinci...... still might be worth going to check out. There are also vendors who occasionally set up with saltwater equipment.
Last one I went to in Columbus was $5 to get in, and the the gift bag had a $20 Drs. Foster & Smith gift certificate plus a bunch of other goodies.
