  However, in the conventional aquarium water filtration device described above, the bacteria are propagated by adhering the bacteria to the filtration mat material, etc., but since this filtration mat material is also a filter, the filtration mat material is circulated. However, there is a problem in that oxygen necessary for the growth of aerobic bacteria including nitrifying bacteria that oxidize and decompose organic matter such as food residues and excrement of appetite fish and ammonia nitrogen cannot be supplied.

  In addition, many of these filter mat materials use fibers, and those made of these fibers may collapse if organic matter such as food residue or appetite excrement adheres to the surface and is thrown away. And the presence of this crushed part creates a specific guiding channel in the filter mat material, making it impossible to effectively use the entire filtering mat material, and the water contaminated by the specific guiding channel remains intact. Since it passes, the problem of deteriorating the water quality occurred.

  Therefore, such an aquarium water filtration device needs to be cleaned regularly. However, when cleaning this device, it is troublesome and troublesome, and it is difficult to use in general households. It was. Moreover, the structure of a filtering device for use in a general home is complicated, and the manufacturing cost is high.

  Accordingly, the present invention has been made in view of the above-described conventional problems, and provides a water tank purification apparatus that has an extremely excellent water purification capability and that has a relatively simple structure and a very low manufacturing cost. To do.

  The present invention is a purification device attached to a water tank, wherein the purification device includes a pump part for circulating water and a water conduit pipe part for purifying water, and the inside of the water conduit part is filled with a filtering material. As a result, the above-mentioned problems have been solved.

  Further, the purification device is attached to the lower part of the water tank, and the purification device includes a pump part for circulating water and a water conduit part for purifying water, and the inside of the water conduit part is filled with a filtering material. As a result, the above-mentioned problem has been solved.

  Furthermore, the purification device is attached to the upper part of the water tank, and the purification device includes a pump part for circulating water and a water guide pipe part for purifying water, and the inside of the water guide pipe part is filled with a filtering material. This solves the same problem as described above.

  Further, the purification device is attached to a side portion in the water tank, and the purification device includes a pump portion for circulating water and a water conduit tube portion for purifying water, and the inside of the water conduit portion is filled with a filtering material. As a result, the above-mentioned problem has been solved.

  In addition, the filter material is formed by cutting a plastic rod having an appropriate cross section into a spiral shape with a small pitch in the axial direction and cutting it to an appropriate length, thereby solving the above-mentioned problem.

  Further, the filter medium is formed such that a plastic plate member formed in a substantially fan-shaped belt shape is bent in a substantially S-shape in a zigzag shape, and twisted and bent multiple times to form a spiral overall shape. The problem described above has been solved.

  In addition, the said water guide pipe part was formed in the folding structure, and the problem mentioned above was solved similarly by the cover being attached to the edge part.

  In addition, the pump unit is provided with a water discharge pipe, and a filter is disposed at the water suction port of the water conduit portion, thereby solving the above-described problem.

  When the aquarium purification device configured as described above introduces and circulates water from the aquarium into the water conduit, organic matter such as food residue and appetite excrement adheres to the surface of the filter medium and fine gaps. Since only water flows through the rough gaps in the filter medium, the water in the aquarium can be purified cleanly.

  In addition, aerobic bacteria and anaerobic bacteria are deposited on the surface of the filter medium, and aerobic bacteria and anaerobic bacteria are also present in the water in the aquarium. It can be purified in an extremely short time.

  Furthermore, since this water tank purification device has a relatively simple structure, the manufacturing cost is very low. Further, since the purification device is simply placed on the bottom, upper side or side of the water tank, there is no need to process the water tank, and the purification device can be installed in the water tank very easily.

  In addition, unlike the conventional aquarium water filtration device, clogging does not occur in the water conduit and no specific guiding water channel is formed.
