Hey, I just inherited all this homebrew stuff and equipment to make a kegerator with. I got the cornelius kegs and that same sanyo fridge a lot of the folks on the boards seem to be using. The process seems straightforward I'm just hung up on a couple things with the CO2. I've got 3 cornelius kegs, and 1 20lb tank... I can fit 2 kegs ez into the fridge but would like to downgrade to a 5lb or a couple 2.5lb tanks so I can get 2 kegs and the gas to fit neatly inside the fridge. In trying to trade down for a smaller tank and someone said I should use a 20oz paintball tank but need to buy some adapter for it. If I'm using the co2 not only for getting the beer out of the kegs but also for getting the gas mixed in the beer is 20oz enough?
