Description

Technical Field

[0001] The invention belongs to the technical field of fish tanks, and in particular relates to a fish tank filtering system. Background Art

[0002] A fish tank is a water tank for holding live fish. The tank body is transparent and mostly made of glass. It can also be used to raise tropical fish or goldfish for ornamental purposes. As people's quality of life continues to improve, they often use fish tanks to raise ornamental fish at home. The fish need to be fed during their growth, and the metabolic waste produced by the fish will be directly discharged into the fish tank. If the water quality is not filtered in time, the water will turn yellow and smelly. The quality of water filtration directly affects the growth and reproduction of fish. The existing fish tank filtration mechanism makes it easy for some larger floating objects to adhere to the filter element during filtration, causing blockage and affecting the filtration effect.
