O2 Carbonation Stone Sizing

[twilsonbrewpc]

Looking at inline oxygenation system and trying to figure out which pore sizing for the stones is best. I'm thinking 0.5 micron is better than 2 micron since the bubbles will be smaller and dissolve quicker. Any thoughts?

Also, I'm brewing on a nano-nano system (10-gal). I have a Chugger pump I use for transferring from HLT to MLT. Should I use a pump to transfer wort through plate chiller and oxygenation system, or will gravity work?

Thanks in advance!

Your are quite correct that, all else being equal, smaller bubbles = better dissolution rate (as a rule). As you'll probably have figured already it's not that simple, however!

Other factors like pressure and temperature are important in trying to get gas to dissolve; a reduction in temperature of just a few degrees can be worth far more than smaller bubbles.

Hope that helps!

I can imagine there are quite a few variables. I ended up getting an inline system w/ a 2-micron stone because that was all I could find for small diameter piping and a small system. Unfortunately the design apparently doesn't allow for changing the stone out, but I'll check it out when I get it. I'm sure any amount of D.O. from it will be greater than what I get now just splashing wort.

Thanks!
