I'm looking for help with setting carbonation & dispense settings for my system. I have a full-size fridge with (2) 5 gallon corny kegs, a 5 gallon Co2 tank, a KegCo dual regulator for independent PSI adjustment, and 3/16" i.d. gas lines; one is 5' long, and the other is 10' long. I remain confused about properly setting carb levels vs. dispense levels. Any help would be greatly appreciated. Thanks!
