On Midwest Supplies' site, they have these instructions for using a 0.5 micron carbonating stone:
Now I attached my 0.5 micron stone as suggested in the instructions, gradually increased the psi as instructed, but the beer did not carbonate in 1/2 hour. In fact, the beer has been sitting for several days at about 17 psi at 32 F, and it is still not at the desired level of carbonation. Has anyone successfully used the instructions above? Is it truly possible to carbonate a beer in 30 minutes (or even several hours) using a carbonating stone as suggested above?
Using a carbonation stone will cut down the time needed to carbonate the beer to about 1/2 hour.
The beer needs to be cold, between 34 and 40 °F.
Attach the stone so that it is at or near the bottom of the keg.
Start with no pressure on the regulator and increase to 1-2 psi and let sit for about 4-5 minutes. You should hear the bubbles in the keg.
Repeat the pressure increase in 1-2 psi increments waiting 4-5 minutes between increases until you are about 14-16 psi.
Try a sample glass. If this is the desired carbonation level, you can either remove or leave in the stone and back pressure down to serving psi. If not, keep increasing the psi in 1-2 psi increments till you get your desired level.
