Co2 Regulator & Diffuser - Which is the problem?
I've got a regulator I bought from an LFS and a glass diffuser. Here is my issue. I open the valve to a setting and then dial in the rate of Co2 with the needle valve. After a a minute or so the rate slows. It seems to not have enough pressure to keep the Co2 pumping out at the same rate I set it. So I open the main valve a little more and reset the needle to where I want and again after a minute or so the rate slows too much. Doesn't seem to matter how much I have the main regulator valve open or how much I dial in with the needle valve.
The only way, it appears, to not have it slow down is to have it open far too much where the Co2 is just pouring out.
What is my issue?
#1. Poor quality regulator?
#2. Diffuser/check valve creating too much back pressure?
#3. User Error?
Thanks for the feedback.
