Hi, I just bought a used two-tap kegerator and 4 ball-lock corny kegs and I have 2 batches fermenting that should be ready to keg in about a week for one and two weeks for the second. my goal is to always have two different beers kegged in the kegerator and one more on standby. Anyway, I am looking for a routine for this set-up. Should I get a second CO2 tank so I don't have to pull my original tank out of the fridge everytime I want to clean and sanitize my kegs? Should I use the 2nd CO2 tank to carbonate outside the fridge? Is there anyone out there with this kid of setup with a routine that works? I am excited about kegging and thanks for all your great information.
