is that a storebought co2 system or one of the homeade yeast ones? i've heard the homeade ones can be unpredictable :-/
It’s one I got online. All the tubing and metal parts come pre-assembled, then it has a recipe to produce the CO2 with citric acid and baking soda. Unpredictable in what way?? The only thing I really see that could go wrong is it running out of CO2, which isn’t a big deal.
