Hey Rich,
I use the full size versions of the Prodibio products. The "nano" versions are only rated for up to 10 gallons, and I've only seen them sold in packs that also include the Iodine and Strontium supplements (which I don't use). I dillute the BioDigest and Bioptim in a cup of tank water but only use about 3/4 of it.
I do not use vodka or any other carbon source; Bioptim is the carbon source made by Prodibio, and BioDigest is the bacteria source (they just strap fancy names on them). You could use a different carbon source for daily dosing if you want such as vodka... Eric of glassbox design uses BioDigest as a bacteria source and vodka, sugar and vinegar as carbon sources (dubbed "V.S.V. method").
