So my co2 regulator is working at nearly 75psi for a co2 artinline diffuser no matter what I turn it to if I open the needle valve fully it drops but as soon as I close it to a normalish bubble rate the pressure rises again to between 75 and 80 is there a issue with the reg

Cheers
Jay

Even with the diffuser disconnected the working pressure is still at 80 psi and it makes no difference changing the psi pressure valve

Try adjusting the grub screw on the bottom of the reg, my bet is that it will be wound all the way in, wind it out a bit and it should drop, not too much though or it'll leak (check for leaks after adjusting)
