The present invention relates to a landscape aquarium filtering system, which is provided with at least two filtering tanks vertically stacked on each other. The interior of the tank is divided by a partition into a filtering tank in which the filtering material may be disposed, and an overflow tank. The bottom of the partition is formed with water channels for communicating the filtering tank with the overflow tank. A sewage outlet is disposed on the lower side of the filtering tank and connected with a sewage pipe. A water inlet is disposed on the upper side of the topmost filtering tank and connected with a water inlet pipe. A lift (submersible) pump is used to pump the pool water into the filtering tank for filtration. An overflow pipe is disposed on the upper side of the overflow tank. The overflow pipe of the upper layer may transport the clean water that has been filtered by the layer to a purifying tank of the lower layer for further filtration. The bottommost overflow pipe is connected with a water drainage pipe for transporting the filtered clean water back to the landscape pool, so as to achieve the effect of water quality purification.一種景觀水族過濾系統，主要係設有至少二呈上下相互堆疊設置之過濾箱，箱體內部則透過一隔板區隔成一可供濾材設置之濾化槽及一溢流槽，並於隔板底部形成有相通之水道，且濾化槽下位處設有與污水管路相接之排污口，而於最頂層之濾化槽上位處則設有與進水管路相接之注水口，可透過抽水(沉水)泵將池水抽入該過濾箱中過濾，另於溢流槽上位處設有溢流管，而上層之溢流管可將該層過濾後之淨水輸往下層淨化槽中再次過濾，而最底層之溢流管則與排水管路連接，以將濾化後之淨水輸回至景觀池中，藉此，使池水達到水質淨化之功效。
