I'd agree with your days and times although most days are do able for me during those hours. As far as topics...
SW- Coral propagation, fragging, lighting and flow requirements, "reef safe" fish and inverts, fish to avoid (i.e. Mandarins, Cleaner wrasses, Harlequin shrimp, Catalina Gobies, etc.), diseases and treatments, dosing, + 1000 others.
FW- Plant lighting requirements, plant safe fish, proper tank size for popular fish in the trade (i.e. Oscars, Clown loaches, etc.), breeding concerns and requirements, pH myths and truths, diseases and treatments, compatibility, invert selection, + 1000 others.
This sounds like a great idea and I'm looking forward to seeing it come together!
