How to make a fish tank filter (preferably with a picture)

The required materials are: fish tank 120*55*60, and submersible pump with flow rate of 4,500 liters/hour is selected as the water pump. Filter materials include filter cotton (physical filtration), activated carbon (chemical filtration), biochemical ball (biological filtration) and ceramic ring (biological filtration). Captive fish species: arhat fish.

1. Put a piece of glass with a width of 52*52 on one side of 18cm to overflow, and glue the two sides and the lower part with glass glue; Make a hole in the lower left corner of the glass, which is equal to the water inlet of the pump;

2. Arrange a piece of glass with a width of 52*40 cm on the outside of the overflow glass, which is used to block water, and both sides are glued with glass; 8.5 cm is reserved at the lower part for grid configuration;

3. When the waterproof glass is glued, stick a grating on it and above it. Grille can be customized in plexiglass shop, and the dimensions are as follows: lower overflow grille 52* 10, upper overflow grille 52*6, grille hole 5 * 0.5cm, and the lower grille is perforated, the size and position are the same as that of the water pump; Bonding with glass glue;

4, arrange the water pump and inlet and outlet pipe fittings; The water pump is installed in the master cylinder; The water inlet pipe directly passes through the bottom of the agreed filter; The outlet pipe is slightly lower than the water surface and exits diagonally;

5. Divide the filter tank into 3-4 parts with glass strips as required, and put them into the furnace row after being firmly bonded; You can use plexiglass, which has a small aperture and is similar to a grid; The grate is detachable, so don't stick it in the glass rod or filter; The bottom layer is above the water inlet pipe of the water pump, and the top layer is lower than the overflow glass, and the reserved space can be used for placing filter cotton;

6. Arranging glass rings, biochemical balls, activated carbon and filter cotton in sequence from bottom to top; When the fish tank is running, the highest water level shall not exceed the grate on the top of the glass ring, and the lowest water level shall not be lower than the grate on the bottom of the glass ring; Pay attention to inspection at ordinary times and add water in time to prevent the pump from burning out;

7. Cut trimming strips or stickers according to the required width and length, and place them in the upper and lower parts of the aquarium; If it's for elegance, it's best to cover the side filters together.

In this way, the side filtration and reverse filtration of the fish tank are done.
