ABSTRACT:
An aquarium filtering apparatus having a spiral prefilter connected between a siphon input line and a return water line for removing floating debris wherein the return line cycles a portion of the return water through a "dry" biological filter for decomposing biological waste and through a chemical stage filter for eliminating undesirable chemical waste from the aquarium water, the filtering apparatus further including a concentric tube arrangement having an outer inlet tube for receiving water from the spiral prefilter and an inner inlet tube for receiving water from the chemical stage filter, the prefilter operating in paralle with the biological and chemical stage filters permitting the concentric tube arrangement to maintain a pair of water levels within the aquarium filter by utilizing a single submersible pump, the pair of water levels ensuring that the pump remains submersible and the biological filter remains non-submersible which minimizes filter recycling time and improves filter efficiency while being packaged in a single compact unit.
