Brand model: Sensen bottom filter fish tank

System: HE-480

The principle of the bottom filter fish tank is to let the water in the fish tank The water flows into the filtration device, is filtered through two physical and biological filtration zones, and is then pumped back into the fish tank by the water pump. When the water level in the fish tank is too high, water will enter the overflow area. The overflow area is connected to the filtration equipment below. The excess water enters the filtration equipment, then passes through the filtration and purification in the physical area and biochemical area, and flows into the water pump area. There is a water pump in the water pump area, and then the water is pumped back into the fish tank to complete the filtration.

Bottom filter is a type of fish tank filtration method. It can provide the largest space for filter materials and is conducive to the cultivation of nitrifying bacteria. The disadvantage is that it is huge in size, takes up space in the bottom cabinet of the fish tank and requires high water pumps. . Usually there are physical filtration area, biological filtration area, equipment area and sedimentation bin. The bottom filter tank is usually hidden in the bottom cabinet. It looks beautiful and tidy overall. Water changes and other operations can be performed in the bottom tank, which can significantly reduce the impact on the fish in the tank.

Advantages of the bottom filter fish tank: The bottom filter provides the largest space for the filter material, so the processing capacity is the strongest (note that it is not efficient). Conducive to the cultivation of nitrifying bacteria. Generally speaking, the bottom filter has 3 or 4 grids. The order of placement of filter materials is: the first grid, white cotton, rattan cotton, the second grid; bacteria house, ceramic ring, glass ring, filter ball, etc. (you can choose one (can also be used together); in the third grid, if it is the last grid, you can put the pump and heating rod. If not, you can also put the bacteria house or medical stone; but you need to leave one grid at the end for the pump and heating rod. Heating rod.

Disadvantages of the bottom-filtered fish tank: The large size usually takes up space in the bottom cabinet of the fish tank, and the requirements for the water pump are relatively high, and the power consumption is relatively large. The water pump must be properly coordinated with the overflow, otherwise the water may flood the mountain or The water pump is dry. Therefore, the technical level requirements are slightly higher.
