The chemisty side of reef keeping is something that keeps me interested in the hobby, with that said I thought a discussion of carbon dosing would be nice. Anything from vodka, vinegar, sugar, bio pellets or anything new that might be out there. I have always thought this was a good article on vodka dosing basics.

So, what do you guys think? What have you tried? What good and or bad have you learned?
