This system uses filtered air to add oxygen to your wort. It is an inexpensive, easy, efficient, sanitary way to achieve wort oxygen levels of up to 8 ppm. The aeration system uses an aquarium pump to force air through an in-line HEPA filter and then through a stainless steel diffusion stone into your wort. This system will never run out of oxygen; however you do need to let the system run for 20-60 minutes to achieve oxygen saturation. Make sure to check on the progress occasionally as it can create a lot of foam.
Note: The filter should never get wet, so don't try and sanitize it by dunking it in sanitizer. To store the filter, use a little tinfoil on the "In" of the filter and store in a zip-lock bag.
