Sweeeet...that'd be awesome!
I was asked to give a presentation on Aquarium Pests and Treatments, but decided since this is our "membership drive", that I'd give the presentation on "Introduction to the Saltwater Aquarium Hobby". The presentation does include a small section on pests and treatment, as well as the anatomy of corals, basic chemistry, some equipment, problems facing the hobby, etc. Even if you're an experienced aquarist, I think everyone will still learn something. Plus, there are some pretty cool pictures.
I can give the Pests presentation in a few months (I just gave it 6 months ago...I'd like to wait a bit longer to give it again.)
