I went to MACNA in Atlanta last September and Eric Borneman did a talk about coral nutrition, during his talk he touched on vodka dosing a little. He recommended against it and said it can lead to coral mortality and provide conditions where pathogens can thrive. He went on to saying the ramifications of long term dosing are risky and not fully understood, experienced reefers have had mysterious disease outbreaks that were devastating. Maybe vodka is best left as a drink instead of a quick and easy cure-all.
