How to replace the filter screen on the fish tank with the filter screen at the bottom?

1, first remove the sewer, and then seal the sewer with glass and good glass glue. This step will take at least 3 days. Drain all the water and seal the inner layer of the fish tank with glass.

2. Then it is necessary to strengthen the bearing capacity of aquarium glass, because the upper filter screen should be placed on the aquarium, and the aquarium glass of the lower filter screen is not as thick as the upper filter screen. So it's best to measure the bearing capacity of the glass, and then use wood or other objects as a cross frame for placing the upper filter.

3. Finally, put the water pump up from the bottom filter screen, buy PVC pipes and re-lay the water flow pipeline from the bottom of the glass cylinder to the upper filter port, set up the upper filter screen and set up the lower drain port (generally, the filtered water falls louder, and the water falls louder), thus completing the transformation.
