I'm going to buy an oxygen regulator and a diffusion stone setup but I need to know which stone size is the best for doing the pure oxygen thing for the wort. Williams brewing sells a setup with a 2 micron and Northern Brewer sells one with a .5 micron.
Does it even matter? It it just longer time with the 2 micron? Thanks!

IIRC the 2 micron stone is usually used for air pumps since fish tank air pumps aren't real strong UNLESS you start spending more $$ for the large pumps (a Whisper 10 is for a standard shape 10 gallon tank, a Whisper 20 is for a standard shape 20 gallon tank, etc). the .5 micron stone is for O2 bottles since the pressure you are dealing with is much higher (even after a regulator) then you'll get with a air pump.
