Abstract
An aerobic filter which comprises a chamber for holding a medium for aerobic bacterial growth. The chamber is positioned to receive filtered water from a primary file which at least physically filters contaminated aquarium water. The chamber is also positioned to be at least partially out of the aquarium water to provide oxygenation of the aerobic bacteria to enhance their growth, and to directly return the aerobically filtered water to the aquarium.
