Very good explanation, reefkprZ. The whole vodka craze just picked back up not too long ago because a lot of reefers in Europe are going back to it. I saw a magnificent SPS tank by a guy in Germany and the vodka method is what he uses to keep the tank clean. He showed growth photos of his SPS corals and it was incredible.
Me personally, I would rather stick with my water changes and know that I am not doing anything that could potentially wipe out my whole tank.
