Carbonate your beer just like the pros with this 0.5 micron carbonating stone with 1/4" barb. Simply attach one end to a couple of feet of 1/4" tubing to the end of the dip tube inside of the keg, and the other end to the stone. Make sure you attach hose clamps to both connections. Then set your regulator to about 2 psi, and the gas will be forced through the millions of tiny pores in the stone, which dissolves the gas into the liquid. Carbonates your beer overnight. Note: To prevent the pores from getting clogged, we recommend not handling the porous end directly with your fingers.
