Vodka, vinegar and biopellets all add carbon into your system, which is a limiting nutrient for bacteriological growth. The bacteria then grow much faster taking up Nitrogen, Phosphate and the added carbon in the process. Whether you add the carbon as vodka or biopellets has little to no effect on the rate of bacterial growth, and thus the uptake and removal of the nutrients by your skimmer.
