About Physical Filtration
The most obvious feature of biological Filtration is the physical filtration. When the water passes through the filter cylinders, large size dirt will be stacked and stopped by the biological filter media. Dirt will be stick between the biological filter and filler. If the biological filter media is closely linked by water pressure, the smaller dirt will be blocked too. The biological filter media and dirt will be accumulated after certain period of time. Then the backwash function can discharge fish waste and impurities, so that the water can be purified. This is the basic principle of physical filtration.
About Biological Filtration
Biological filtration refer to the breeding of beneficial bacteria inside the cylinder attached to the filtration media after certain period of time. The formation of a thin biofilm by the beneficial bacteria can efficiently convert the ammonia and industrial nitrate inside the filter into nitrate and then digested.
