Additional Information
Whisper Aeration Pump
Instead of diffusing pure oxygen into your wort use filtered air. Use the Whisper Aeration Pump to push air through a two micron diffusion stone. The advantage of an aeration system is that you never have to buy replacement oxygen tanks. The down side is that aeration takes longer than oxygenation. Because the atmosphere is only about 20% oxygen, the diffusion stone must be left running in the wort for approximately 30–120 minutes (however even 5 minutes of aeration is better than shaking the carboy.) There is no concern of contamination during this period, however you do have to monitor the fermenter periodically for possible over foaming.
