Well, let's see.
16 gallons X 128 oz/gal = 2048 ounces in your tank
2048 X 2% (0.02) = 41 ounces of alcohol in full tank of water is 2% alcohol.
Since 80 proof is 40% alcohol, you need 100 ounces of 80 proof vodka, or nearly one gallon in a full tank for 2%.
That is why I only have one or two gallons in my tank to disinfect it. That way I only need 3-6 ounces of 80 proof vodka. One bottle will last many seasons.
