I'd say almost definitely a leak somewhere; I'm supplying a much larger
tank, with a cylinder 1/3 the size, that was improperly filled, for much
longer. Get some soapy water, and test your fittings. Might also invest in
some good CO2 proof tubes if you have long runs (but then some say it makes
no difference, so YMMV).

Cheers,
Poe
