Stainless Steel Carbonation Oxygen Stone - 1/4" OD Barb (2.0 Micron)
Diffusion Stone - 2 Micron Oxygen Stone
Use this 2 micron oxygen stone with an oxygen source or aeration pump to provide your yeast with oxygen pre-fermentation. The barb is 1/4" OD. (Note: if you are using an aeration pump, we recommend a "deep water" type for aquariums, as these will have the necessary PSI to force the air through the stone and into the wort)

Sanitizing your Diffusion Stone: To properly sanitize your stones, we recommend you run it in a sanitized solution for 5 minutes. If the stone becomes clogged we recommend boiling the stone for 1-3 minutes to help break down anything within it. If boiling is not an option, we recommend soaking in Star San, which will remove a majority of surface contamination/bacteria, but will not sanitize the interior of the stone which may or may not be contaminated.

1 of 5 Don't waste your money January 10, 2015
Reviewer: John from Kingston  
Bought one of these, only place air comes out is at the entrance to the stone where the fitting connects, pretty much useless, was going to use to oxygenate my wort prior to pitching yeast, ended up stirring instead.

5 of 5 Very strong a durable diffusion stone November 18, 2013
Reviewer: Guillaume Charbonneau from sainte Victoire de Sorel, QC Canada  
Im planing on using this stone in a inline oxygenation setup right after my couterflow chiller. The construction of the stone looks unbreakable and really neat. My only concern is the pressure needed to push gas though it and clogging of the pores after a long term use. Only time will tell!
