ABSTRACT:
An aquarium system comprising a water-tight fish tank and a screening means that divides the fish tank into an upper section and a lower section, one or more barriers that divide the lower section into two or more separate compartments, and two or more outlet orifices are located in the fish tank bottom. A gravel bed is supported on the screening means. A water pump circulates water from each of the outlet orifices, through a water filter, to the upper section of the fish tank. The velocity of the water circulated through the gravel bed by the water pump flushes any waste material from the gravel bed. A flushing velocity may be maintained because the gravel bed covering each separate compartment may be flushed separately.
