ABSTRACT:
A reef type filtration device is provided in the form of a cylindrical chamber containing a series of bio-balls stacked from top to bottom, has input and output nipples in the top and bottom which can be simply and easily connected into the return line of the standard circulating pump for an aquarium. The addition, an air nozzle in the bottom end cap provides additional oxygen when connected to a standard air pump present in most aquarium installations. The bio balls provide a greatly increased surface area for growth of aerobic bacteria for removing ammonia and other nitrogenous compounds and the air introduces additional oxygen to maximize the growth of the ammonia consuming aerobic bacteria on this greatly increasing surface area.
