This is a combination of a storage type filtration tank 4 called a filtration tank.

The main body 1a of the filtering device 1 to be mounted on the upper surface of the water tank A of the present invention is a box-like shape having the same shape as the upper surface of the water tank A with an open upper side, and the water tank downward to one side. A pipe of a water supply device 5 such as a pumping pump 5a for sucking seawater W from A is provided in a penetrating state, and the tip end side of the pipe of the water supply device 5 is a water spray pipe 5c having a large number of water spray holes 5b. There is something.

The sprinkling pipes 5c are horizontally provided above the physical filtration tank 2 of the filtration device 1 of the present invention, and one or a plurality of the sprinkling pipes 5c are provided.

The first filtering material 2b laid on the upper surface of the water-permeable floor material 2a having a large number of small holes formed in the upper portion of the filtering device 1 of the present invention is a fiber material or a sponge. Is a physical filter tank 2 in which a mat-shaped filter material made of, for example, is laid, and is eliminated by physically filtering solid waste such as residual food and feces with the first filter material 2b. To do.

Next, a partition wall 6 is provided vertically below the physical filtration tank 2 to form a water passage type filtration tank 3 and a storage type filtration tank 4.
Are arranged in parallel, and the area ratio of each is not particularly limited, and is appropriately set depending on the amount of circulating seawater W and the size of the water tank A.

The water-permeable filter tank 3 is called a dry-type filter tank, and the water-permeable filter tank 3 has a bottom surface 3a.
A through hole 3b for outflow is formed in the seawater W, and the seawater W flowing through the first filtration material 2b of the physical filtration tank 2 is supplied in a water drop or water flow state. The seawater W is returned from the through hole 3b to the lower water tank A without being stored, and the natural coral having bacteria such as nitrite bacteria and nitric acid bacteria attached above the bottom surface 3a of the water-permeable filter tank 3. The second filter bed 3c is thickly filled with sand or artificial filter material.

The above-mentioned nitrite bacteria are those which change ammonia, which is a toxic substance, into nitrite as a nutrient source, and further, the nitrate bacteria are those which transform nitrite into nitric acid as a nutrient source, both of which are aerobic bacteria. Therefore, the seawater W is passed through the second filter medium 3c of the water-permeable filter tank 3 so that a large amount of aerobic bacteria are proliferated and at the same time oxygen is supplied to the seawater W.
