How to filter a small fish tank

Many people use submersible pumps (filters) to raise fish. After you buy it, you should connect the attached water hose from the water outlet at the bottom of the cylinder to the water surface, and then filter it from the filter and flow into the water to complete the water cycle. This kind of hose is ugly in water, and it is also difficult to wash when it is dirty because it is soft and threaded. I have an idea: Take the plastic sheathed conduit for electrician (hard and straight) (available in building materials store) and cut it according to the distance from the water pump to the water surface, and connect it with sheath line elbow to make it form a right angle. In this way, the pipe occupies less space in the water, sticks to the edge, and is beautiful and easy to scrub. Might as well try. If there is a surf port, you can connect two water outlets and one to the filter with a tee.
