The simple tutorial on aquarium water circulation is as follows:
1. Lay filter cotton at the bottom of the aquarium for physical filtration, and use four magic mats to separate the dry and wet layers. Rinse it with clean water before placing it.
2. Place a hair ball inside the magic mat to absorb fish excrement. Use 6cm thick fine-pored biochemical cotton under the dry and wet separation to block and isolate impure materials, and finally put it into the mat. bacteria house.
3. After completing physical filtration, purchase a built-in filter. During transportation, hold the outer filter frame with both hands, with the filter seal facing upwards, and avoid collision with hard objects. objects.
4. Insert the rubber vent tube above the built-in filter and keep the wire as far away from it as possible.the water. You can also purchase a sticky glass vacuum head and attach the wire to the edge. of the aquarium wall.
5. Then put the entire built-in filter into the water. In the filter tank, there is a roll-shaped filter cotton wrapped around a leaking cylinder, and adsorption balls are added to the internal space. If the aquarium already has physical filtering, you can leave it alone.
6. Finally, turn on the external switch for operation. As it is built-in, its sound is very light, if noise occurs, check if there is any quality problem after using it for a period. time, simply remove the cotton from the internal filter, take it out and clean it.
7. Inside the biological filtration at the bottom, place and cultivate nitrifying bacteria in the bacteria house. In this way, the aquarium forms naturally circulating biota and there is no need toe change the aquarium for cleaning. The nitrifying bacteria are placed in the hole of the bacteria house and do not float directly to the surface.
