Abstract
An aquarium filter system having a rotatably mounted filter body. The filter body is structured such that when mounted with a portion of the filter body submerged in moving water, rotational movement is imparted to the filter body by the moving water. As a result of the rotational movement, at least a portion of the filter body is alternately exposed to the water and the atmosphere. This fosters the growth of aerobic bacteria on the surface of the filter body. The aerobic bacteria reduces the level of toxins within the aquarium water.
