Aerate your wort automatically with this complete aeration system. Includes compact air pump, air filter, diffusion stone, and EVABarrier tubing. This aeration system diffuses oxygen into your wort using the air around you, so there's no need to buy pure oxygen cylinders again and again. The down side is that aeration takes longer than oxygenation. Because the atmosphere is only about 20% oxygen, the diffusion stone should be left running in the wort for approximately 30 minutes (but even 5 minutes of aeration is better than shaking the carboy). The sterile filter will prevent contamination during this period, but you will need to monitor the fermenter periodically for possible over foaming. To clean your stainless stone, we recommend boiling it for several minutes and storing it in a zip lock bag between uses. It can clog easily with the oil in your fingers, so use gloves when attaching it to the tubing. You will need to cut a short piece of tubing to bridge the connection from the air pump to the air filter and the air filter to the diffusion stone. You do not want the air filter to get wet or be inserted into your fermenter, so keep the air filter close to the pump.
