regulator psi, concentration related

If i turn up the psi on my regulator will the CO2 concentration per bubble increase or just the speed that the bubbles are sent to the diffuser is faster?

All you can really adjust is the working pressure. That's the function of a regulator: to allow the pressure to be adjusted to a safer level (compared to the pressure inside the actual tank). The needle valve is used to control the "speed" with which the co2 is sent to the diffuser.

As far as concentration, all of the gas is ~99.9something percent co2, so you can't adjust this in any way that I'm aware of

the reason why i'm asking is because i currently like the flow of my co2. It's getting diffused nicely with fine bubbles and are getting blown around very well. The faster i set the bps the larger the bubbles are and its harder to get the blown around the tank. I want to increase my CO2 levels without making my bubbles larger. Should i look else where to get this? Would you suggest increasing the psi?

A better diffusion method.

What epic said.

The co2 in your cylinder is something like 99 or 99.5% co2....can't change that. Only thing you can do is increase your bubble rate and find a better way to diffuse it.

or increase the number of diffusors- the down side is you will need a few more connectors, tubing and needle valve too.
