Biochemical ball
Basic content:
Generally made of plastic, mostly spherical, square or irregular, with many protrusions and black. Biochemical ball is also a widely used biochemical filtration material, but its application scope is limited, and its special structure makes it unsuitable for many filtration methods and can not play an efficient role. It is not suitable for external, internal and upward filtration, which will greatly reduce the biochemical effect. Generally speaking, trickle filter is the most suitable. When using, try not to soak all the biochemical balls in water, but let the water flow through, which will bring more oxygen and more parasites.
The selection of biochemical balls generally pays attention to materials and workmanship. Now a new one with biochemical cotton is introduced, which can parasitize more nitrifying bacteria and further improve the biochemical ability of biochemical balls.
The maintenance and cleaning of biochemical balls are basically the same as those of glass rings. For those with biochemical cotton inside, the biochemical cotton inside can be replaced regularly, instead of the whole biochemical ball.
