Well thanks for the replies and info niko and ach. I will go get it refilled tomorrow and I will make sure it is full. My main concern is something is leaking and I missed it somehow, so I took the regulator off and tightened the fittings and I will be getting a new gasket for the tank. I will also be more thorough with my soapy water tests in the future.
Just wondering if the gas line Teflon tape is adequate for co2 fittings?
