There are a lot of "experimentalists" who make this claim or that and put forth a witch's brew of some magic ingredient(s) supposedly performing all kinds of magical events, getting phenomenal results. Without a scientific methods approach to testing, recording and publishing results, I wouldn't use the magic formula. In the case of the vodka elixir, I'm with David on this one with a twist, please. If, after a couple of these elixirs, I want to "feed" the bacteria in my tank to raise their numbers I'll, (well, I'll let you use your imagination as to how I'd feed my bacteria).
Thanks for the link Carmie!
