With a finnecky nv, another way to fine tune your co2 is adjusting the working pressure. You get more co2 running 5bps @ 35psi than you do 5bps @ 20psi. Again, do this adjustment slowly.
Thanks nokturnalkid. I have an Atomic diffuser that I run at 35 psi. Every so often it will creep up to 40 psi at which point I back it off. It makes me nervous running it any higher the 40 psi - though I don't know why.
