Use this 2 micron stone with an oxygen source or an aeration pump to provide your yeast with oxygen pre-fermentation.
This diffusion stone can also be attached to the end of your “gas in” on your keg with 50cm of tubing to rapidly speed up
carbonation.
CLEANING:
This stone can be sanitised in boiling water and cleaned in anon-rinse sanitiser while running
CO2 or air through the stone. If the pores in the stone get blocked from handling give a 10 second dip in hydrochloric acid
before rinsing with water.
