I have a question regarding CO2 reactors and working pressures. So I have read in some other posts here on the forum that for reactors, you generally need less pressure to operate as the only pressure you need to overcome is the water pressure.
How does one know if one has enough working pressure? My intuition tells me that so long as stuff is going into the regulator, congratulations you have enough to operate. And a follow up question is, does this mean that increasing the working pressure doesn't really change how much CO2 is being injected so long as a threshold is being met?
