Homemade simple fish tank water circulation tutorial

Homemade simple fish tank water circulation tutorial is as follows:

1, in the bottom of the fish tank laying filter cotton for physical filtration, wet and dry separation of the double with four magic carpet. Placement of the first rinse with water once.

2, in the magic carpet placed inside the ball adsorption of fish feces, wet and dry separation of the following 6cm thick fine pore biochemical cotton, the impurity blocking isolation, and finally put into the bacteria house.

3, after the completion of the physical filtration to buy the built-in filter, in the process of handling both hands to hold the outer frame of the filter, the filter gasket facing up, do not occur with hard objects collision.

4, the built-in filter will be inserted above the ventilation rubber tube, ventilation wire as far as possible out of the water, you can also buy a sticky glass suction head, the wire will be fixed in the aquarium wall edge.

7, the bottom of the biological filtration inside, placed in the bacteria house to cultivate nitrifying bacteria. So that the fish tank formed a natural cycle of biota, no need to change the tank cleaning, nitrifying bacteria placed in the hole in the fungus house, do not float directly on the surface.
