The bottom filter fish tank is to pump water from the water pump area to the fish tank through 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 with the filtering equipment below, and will first enter the physical area. The water level in the physical area will continue to rise, and the extra water will enter the biochemical area. After that, it will enter the water pump area and return to the fish tank from here.
1. Dry and wet separation: It is a very good combination of bottom filter and dry and wet separation. The method is to add filter cotton to the drip box above the first grid of the bottom filter cylinder. The advantage of this is that it can increase the space of filtration, but also enhance the effect of filtration.
2. Sedimentation area: The bottom filter can also add a sedimentation area. The function of the sedimentation area is to precipitate the fish feces, which can reduce the burden of physical filtration. However, if you do this, you should clean it regularly so as not to accumulate more and more, which will affect the efficiency of filtration.
3. Side filtration: Generally speaking, the filtration effect of bottom filtration is enough. If you want to strengthen the filtration, you can add a side filtration. In this way, an overflow area will be formed on the side, and certain filter materials can be placed inside. However, the overall ornamental effect may be worse.
