The purpose is to remove pollutants such as feces and organic matter in the water to keep the water clear, with sufficient oxygen in the water, and free of harmful substances and pollution, so as to be suitable for the growth of fish. In daily life, setting up a filter in the fish tank can create a good living atmosphere for the fish and can reduce the frequency of water changes, further simplifying the complexity of the operation of raising ornamental fish for users.

[0034] The existing aquarium filter device is one of the various instruments used for fish farming. It is used to purify water quality and supplement oxygen. The purpose is to remove pollutants such as feces and organic matter in the water to keep the water clear, with sufficient oxygen in the water, and free of harmful substances and pollution, so as to be suitable for the growth of fish. In daily life, setting up a filter in the fish tank can create a good living atmosphere for the fish and can reduce the frequency of water changes, further simplifying the complexity of the operation of raising ornamental fish for users.

[0035] In existing designs, most fish tank filters use a water pump as a tool for liquid circulation. A filtering device is set at the water inlet of the water pump. The water pump sucks in water purified by the filtering device and discharges it into the fish tank. It can not only purify the water body, but also increase the oxygen content of the water body after increasing the disturbance of the water body.
