This utility model relates to a fish tank water filtration system, belonging to the category of ornamental fish breeding filtration facilities. The fish tank water filtration system includes a fish tank, a water pump, pipes, and a filter cartridge. A main water intake pipe connects to the inside of the fish tank and is divided into a main filtration pipe and a main flushing pipe via a T-junction. The main filtration pipe and the main flushing pipe are each connected to a T-junction, and the second ports of the two T-junctions are connected via a power pipe, which houses a bidirectional water pump. The third port of the T-junction connected to the main filtration pipe connects to a branch filtration pipe, which has multiple branch tees connected in series. The third port of the T-junction connected to the main flushing pipe connects to a branch flushing pipe, which has multiple branch flushing tees connected in series. A filter cartridge is connected between the branch tees and the branch flushing tees, and filter media is placed inside the filter cartridge. A drain valve is installed at the end of the branch filtration pipe, connecting to external drainage. The end of the branch flushing pipe connects to the inside of the fish tank. This filtration system is placed outside the fish tank and can filter the water inside, maintaining water cleanliness. This device uses a bidirectional motor to achieve both filtration and backwashing, increasing the lifespan of the filter media and avoiding frequent replacements.
