CO2 diffuser question

I have a hard quaestion about building an inline DIY CO2 diffuser. Mine is PVC and is 10" with a diameter of 2". My question deals with the size of bioballs to use inside. I have a whole bunch of 1" balls I might use. I'm interested to know how flow will be affected with either a couple big balls 2" or a bunch of smaller balls 1".

Thanks for any help.

I would suggest considering to leave the bioballs out...

I don't think the size of the balls would matter, because, like Wasser, I don't think bioballs make any difference.

Why would you suggest leaving them out? I would think they would add to the turbulance of the water and increase saturation? I dont' think the size would matter however just as long as it broke up the water allowing for a good mix...?

If you just want to add turbulance, why not just put a faucet screen on the intake and get a spray like effect?

I couldn't find any bioballs at my LFS. So I got coarse filter sponge and cut them into cubes. I was a little worried at first that this would create too much resistance. Works like a charm! I only filled up about 5-6" of it with foam. I get 100% diffusion of CO2. And the water resistance is very little.
