Further, a wool filter 4 is placed on the surface inside the filter media cartridge 2, and the wool filter 4 physically filtrates, and a porous plastic filter 5 is filled inside the filter media cartridge 2 below. -ing

The porous plastic filter material 5 does not perform physical filtration, but rather performs biological filtration by allowing ammonia-degrading bacteria to grow therein. Therefore, the porous plastic filter material 5 has the role of a breeding bed for ammonia-decomposing bacteria.

The seawater filtered by the wool masotho 4 and the ammonia-decomposing grouper in the filtering material cartridge 2 then passes between the oyster shells and coral shells filled in the PH adjusting material cartridge 50, and then flows through the PH adjusting material 6. When acidic seawater passes through, the pH adjusting material 6 melts and adjusts the pH to a neutral pH of 7 to 7.5.

Further, the filtered seawater that has passed through the pH adjusting material 6 is sucked into the water circulation pumps P1 and P2 in FIG. 4 through the suction port 60.

Furthermore, a warming heater 7 is placed at the bottom of the filter tank F to raise the seawater temperature to an appropriate temperature for each transported fish when the seawater temperature is extremely low.

The structure is such that compressed air continues to be sent to 5b to continue supplying air into the aquarium, without weakening the live fish.

In addition, the diaphragm blower 22 sends compressed air to the five filter tank dispersers, but the ammonia-decomposing bacteria that are growing in the porous plastic filter material 5 in the filter tank F will cause the transport of live fish to end. Even later, it is necessary to keep it in an active state at all times.If the air supply stops, anaerobic bacteria will breed, and the ammonia-degrading bacteria necessary for biological filtration will die, so keep supplying air at all times. There is a need for temperature control.
3.64, the amount of air is small but the power consumption is also low so that air can be fed for a long time of 2 to 3 days even when Engine E is stopped.

In addition, when the container N of the present invention is stopped at a container yard, it is configured so that a 220V commercial power supply can be used, and it is used for temperature control.
