Pure oxygen is the best way to get your yeast off to a cracking start.  Simply use this high pressure and high-capacity disposable tank to boost dissolved oxygen levels in your cooled wort.We would recommend the use of a diffusion stone.  These small diffusion stones create very fine bubbles of oxygen in your wort and help the oxygen to dissolve into solution faster.  If you want a really nice option, we would recommend the use of this oxygenation wand.

Remove the protection cap from the valve. 2. Connect the regulator to the cylinder valve. Attach the regulator to the top of your disposable cylinder.  Turn pressure up to 10-20psi.  With a sanitized oxygenation wand with 0.5 or 2 micron stone  immerse the diffusion stone in wort at the lowest possible point for 1-2 minutes. NOTE: Wort must be cold.  It is extremely difficult to get oxygen to dissolve into hot wort so it’s essential to cool wort completely before starting this process. There may be some gas escaping as you’re screwing on so screw the gas cylinder into the regulator quickly to limit this loss, continue to screw on until gas stops.PLEASE NOTE: If you are removing the regulator at any point you MUST use a spanner to hold the brass neck of the cylinder. Failure to do so could cause the strong adhesive glue to crack and the cylinder detach from the fitting. WARNING: Contains gas under pressure, may explode if heated. Pressurised Container, ensure cylinder is empty before disposal. Do not expose to naked flame or any incandescent material. Keep out of reach of children, only use in well ventilated areas.
