I ran the gas line into the fridge then to two tees. then out to the kegs.
If I want different volumes co2 in each keg, I would need more regulators, correct.
Once the beer is carbonated, and all three keg gas lines were connected wouldn't they all equal out over time?
My concern is that I have a porter and a stout I want carbonated at a lower level of carbonation and then a light lager that I want more carbonation in.
