Guys I am trying to determine if I have a leak or not. I just got a new regulator yesterday. I also had my co2 bottle filled yesterday and this morning I find my bottle is almost empty. I know I screwed it on tight and it also has an o ring on the connector to the co2 bottle. This morning when I checked my bubble counter I found my bubbles being pumped out rapidly but it wasn't a steady stream. My fine adjustment must have slipped. What should the pressure be at on the guage to the right?
