If you want to clean the bottom filter of the fish tank, you need to fish out the fish first, take out the equipment in the water, and empty the water, and then take out the filter material and clean it one by one. Usually, the filtration system does not need to be cleaned frequently, at most once a month, too frequent cleaning is not conducive to the establishment of nitrification system, so that the water quality is not well maintained, but also increases the risk of algae explosion.
1. Good filtration effect: The biggest advantage of bottom filtration is good filtration effect. Because there are many filter materials, the filtration capacity is very strong. Compared with the upper filtration and the filter barrel, it can better maintain the water quality. However, this is also very troublesome, that is, because there are many filter materials, it is not convenient to clean up.
2. The noise is relatively small: the overflow area of the bottom filter is mainly at the bottom of the fish tank, and a pump with too much power is not needed, so the noise is relatively small. Low noise is important for fish, because noise may affect their rest, causing them to be in a state of high tension, which is harmful to their health.
3. No space occupation: The bottom filter and the fish tank are integrated. Unlike the upper filter, which needs to be placed on the top of the fish tank, and unlike the filter cartridge, which needs to be placed outside, the bottom filter is located at the bottom of the fish tank. The occupied space is very small. However, it is only suitable for large fish tanks. The bottom filter in the shape of a small fish tank is still somewhat wasteful.
