If you want to adjust the water level of the bottom filter fish tank, you need to remove the cover plate, pull out the outlet pipe, remove the outer package pipe, measure the depth, and saw it off at a suitable place. Usually two holes can be punched in the lid, which can facilitate the temperature probe thermometry, but also can wear an oxygen tube oxygen. Put oxygen in the overflow area, and you can lower the water level.
1. Low noise: Because the filtration equipment is at the bottom of the fish tank, there is no need for a pump to pump out the water, so there will not be too much noise. Noise will not only affect people's rest, but also have some harm to the fish, continuous noise will lead to some stress response of the fish, affecting its health.
2. Strong filtration: As the number of filter materials is relatively large, the filtration capacity is relatively perfect, and all the effects are relatively good, which can well maintain the water quality and reduce the water change cycle. However, it is precisely because the number of filter materials is relatively large that it is difficult to clean and replace them.
3. More beautiful: Compared with other filtering equipment, the bottom filter is at the bottom of the fish tank, which basically does not affect the viewing, unlike the upper filter which occupies the space above the fish tank, and unlike the filter cartridge which is placed outside, the bottom filter and the fish tank as a whole look more beautiful.
