I suppose the nutrient poor situation would also apply to those folks that advocate adding vodka or any of the other low molecular weight organic compounds.
Yes, although according RHF the people in europe that started the vodka thing say that vodka promotes different bacteria species than acetate. I've never seen any real study that identified exactly which bacteria species were responsible for nitrogen fixation and phosphate reduction so I don't know how they make the claim. I guess we are supposed to just accept that vodka bacteria are better than acetate bacteria because drinking vodka is better than drinking vinegar LOL.
