About the setup I'm using...that 2nd bottle. Would not all the O2 in that bottle need to be forced out before you start seeing CO2 enter the tank (you'd still see bubbles, but they wouldn't be CO2)
I saw 4 bubbles randomly get pushed out in sucession, but then nothing after that. There seems to be a bubble formed at the end of the air line, but it's just kinda sitting there.
