    Once you reach into the green that bottle is going to be impossible to squeeze unless you like the hulk or something hence using the needle valve to release some pressure causing citric to flow over into the solution.

    Okay I will give it another try tonight using multiple squeezings and releasings of pressure. Last night I managed to get about 2 hours of constant CO2 bubbles in the tank. That was with one squeeze and about 2 minutes waiting before releasing pressure.

    I got the needle to move just a fraction. The citric acid bottle did become impossible to squeeze anymore. So far the CO2 has been going for about an hour.

    After it was impossible to squeeze did you continue to use the needle valve to build the pressure?

    I did leave it closed for a bit but the needle only went to the 1st marking. I am planning to replace both the solutions tomorrow and give it another go. I am fairly sure now that its just a technique issue from my side. I guess I will have to watch the video again more carefully this time.

    Yeah you must not just leave it closed. You need to open it wide so the gas escapes and that's cause solution from A to be sucked into B. Then you close it shut as the two solutions mix. You need to repeat this about 4 or 5 times to get the pressure up.
