The present invention relates to an aquarium filtration water purification device for filtration and purification of suspended solids and foreign substances in the aquarium, by providing fluidity to the microorganism filtration water purification material in the filtration tank to improve the flow of water (sea water) and filtration water purification function It is an object of the present invention to provide an filtration water purification device for an aquarium that can effectively filter and filter water in an aquarium containing fish species. That is, this invention divides the inside of the main body 2 into the partition 3, and consists of the 1st, 2nd filtration chamber 5 filled with the filtration water purification material 11, The flow path 6 which connects these in the lower part In the upper portion of the first filtering chamber (4), the bubble generating tank (7) is formed by partitioning into a horizontal plate (8), the bottom (4a) of the first and second filtering chambers (4) (5) ( 5a) and the horizontal plate 8 are densely penetrated by several holes 4b, 5b, and 8a, and a pressure pump 14 and an air supply pipe 15 are installed in the first filtering chamber 4 in the middle. For the aquarium in which the contaminated water supply pipe 13 for supplying the contaminated water supply pipe 13 of the aquarium 100 is installed in the vertical direction, and the bubble outlet 9 is installed above the bubble generating tank 7. In constituting the filtration water purifier 1, the water supply pipe 13 is piped to the lower portion of the bubble generating tube 12, the bubble generating tube 12 is a water passing through the first filtration chamber 4 at the bottom Nozzles 12a are formed, and the foaming tank 7 A bubble generating hole 12b is formed on the exposed side, and a water drain pipe 18 connected to the aquarium 100 is piped to the second filtration chamber 5, and a strainer 19 is installed at the inlet. By finally filtering the debris passed throu
