to put the filter material at the bottom of the fish tank? It is possible to put the filter material at the bottom of the fish tank, but it is not recommended to do so. On the one hand, a large number of filter materials in the fish tank will greatly affect the ornamental, on the other hand, because of the limited mobility of the water in the tank, the efficiency of filtration is relatively low, and the effect of maintaining water quality is not as good as that in the filter box. It should be noted that the filter material in the filter is placed in order, and the water flows back to the tank through the pump after physical filtration, chemical filtration and biological filtration.
the filter material 1. Physical filtration: Physical filtration is the first step of filtration. Its function is to leave impurities and dirt in the water. Usually, the filter material chosen is cellucotton, which should be placed in the first layer of filter box. Socks can also be put on the outlet pipe mouth, which can achieve a similar effect, and cleaning is also very convenient.
2. Chemical filtration: Chemical filtration is generally carried out after physical filtration. The main filter materials are activated carbon, ammonia absorption stone, zeolite and clean water resin, which can absorb harmful substances in water, but the adsorption effect is limited. It is usually replaced once every three months.
3. Biofiltration: Biofiltration is the last one placed in the filtration equipment, generally including biochemical cotton, biochemical balls, porcelain rings, etc. The main function of these filter materials is to cultivate nitrifying bacteria, which are of great help to the maintenance of water quality, so they are also essential.
