Diffusion Stone – 2 Micron Oxyg

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)
