My first pressurized co2. I have the Dr. Foster Smith full auto setup. It came with little to no instructions. Its set up like the picture but I think I'm doing something wrong with the reactor. It keeps back flowing water/ pressure into the bubble counter. I've gone through two bubble counters and now I think the regulator has stopped working. I turned the valve slowly and it dumped a lot of gas into the bubble counter and dumped into the tank. I disconnected everything, and I couldn't get any bubbles out of the reg alone. The working pressure gauge seems to be stuck at 60 Psi even when closed. I just planted a full tank and using flourish excel for a day now. Anyone used this setup?
