How to use fish tank filter

1. Put a filter cotton on the bottom of the fish tank for physical filtration, and use four magic blankets for dry-wet separation. Rinse with clear water before placing.

2. Put the wool ball in the magic carpet to absorb fish dung, dry and wet separate it with 6cm thick fine-hole biochemical cotton to block and isolate impurities, and finally put it in the bacteria room.

3. Buy a built-in filter screen after physical filtration. Hold the outer frame of the filter with both hands when handling, so that the gasket of the filter faces upwards to avoid collision with hard objects.

4. Insert the ventilation rubber tube above the built-in filter, and try to keep the fire wire out of contact with water. You can also buy a glass-attached suction head and fix the wire on the wall of the fish tank.

5. Then put the whole built-in filter into the water. In the filter tank, a drum-shaped filter cotton is wound around a cylinder that leaks through the net, and an adsorption ball is added in the inner space. If the fish tank has been physically filtered, it is not necessary.

6. Finally, turn on the external switch for operation. Because it is built-in, the sound is very light. If there is noise, it depends on whether there is quality problem. After a period of use, just take out the filter cotton inside and clean it.

7. In the bottom biofiltration, nitrifying bacteria are cultured in a bacteria room. In this way, the fish tank forms a natural circulation biota, and there is no need to change the tank for cleaning. Nitrifying bacteria should be placed in the hole in the mushroom house, not directly floating on the surface.
