Go slow on the vodka and read a lot before diving in. You also better have good tests for nitrate, and phosphate before you start as you will be using them a lot in the beginning. I dabble with the vodka in my 75 (as well as in my tonic with some lime) once you have it dialed in you will need to feed a lot. It is a lot of work to be warned. Also, your alkalinity is even more important once you get to the ulns. Good Luck with whatever avenue you choose.
