I have a pressurized CO2 system. My problem is that when the bottle nears empty the needle valve will let the bottle empty rather quickly. It will go from 2 bubbles a second to 8 or 10 (basically uncountable). It sends my Ph down .6 to .8 below normal. If I catch the problem the needle valve can be readjusted back to 2 bubbles a second. I tend to lose a fish or two each time it happens.
I've heard about this problem happening to others but I don't remember the solution. Also I have a system made for aquarists, not a home made one from a welding shop.
