Everything is wrong with what I am trying to do, but it's where I'm at... lol!
I'm using a 20oz paintball co2 tank to try and carbonate 2.5 gallons of beer in a 5 gallon corny with little success. Everything pressurizes great, no leaks, regulator works, beer pours fine, nice head. In summary, everything seems to be right but I can only get minimal carbonation in the beer. I've done three batches in three different kegs thinking maybe there is a small leak I couldn't detect but ended with the same results. I've ramped up the psi to over 30 and left it on gas for up to 7 days on the third batch.
A few of caveats to consider. Its 2.5 gallons in a 5 gallon keg, the beer is warm (55 f), and its a tiny paintball tank. Like i said, everything I am trying to do is wrong.
Is the warm temp of the beer making it hard for co2 to absorb? Is that size tank to small for anything but serving?
I am newer to the keg scene and any advice would be appreciated!
