I am not sure why it matters whether bubbles come out at regular intervals or not. Watching ADA videos where all the tanks have pressurized gas I see all sorts of intervals going on. Just count bubbles per minute and once BPM drop recharge the system.

Here is one showing this, see the second tank. Bubbles build up in the crook then 123---123---.
