Rob,
Just a minor correction to your logic on vodka and sugar dosing. Vodka and sugar are found in the ocean, just not called as such. Sugar is a byproduct of photosynthesis, and as we all know there is alot of that going on in the reef system. As far as vodka. Where there is sugar, bacteria, and a temperature in the 80F area or above there will be fermentation. The byproduct of tis is alcohol. So as far as your statement of it not being in the reef you are partly right. The proper sugars should be glucose, and dextrose, but simple table sugar when heated and combined with water converts to an inverted sugar (glucose, and sucrose). My chemistry may be a little of, but the principal is sound.
