These bacteria attach themselves to the sand media in the filter chamber. As water is pumped through the filter, the sand grains and their bacteria are constantly bathed in a fresh supply of nutrients and oxygen, creating extremely efficient biological filtration for your aquarium. The continuous movement of the media also helps ensure that detritus does not build up, and this "self-cleaning" action permits a relatively constant level of bacteria to inhabit the sand media. You'll love the convenient, reliable, and easy-to-use engineering of these filters.Please click on "More Information" for specifications.
