Generally, the oxygen pump should be placed outside the fish tank where it can't touch the water, so as to avoid damage after touching the water. It should be noted that the oxygen pump must be higher than the water level, otherwise it will produce siphon phenomenon, resulting in water from the cylinder into the oxygen pump. In addition, it is better to place it in the air or on a cushion to prevent vibration, so as to reduce noise. Near the cylinder block, reduce the length of the air duct.
1. Filtration system: Fish farming generally requires a filtration system, and most filters will produce water flow, bringing gas into the water to increase the dissolved oxygen. It should be noted that the filtration system must match the size of the fish tank, if the fish tank is too large, the filtration power is not enough, it is a drop in the bucket, can not play a role. On the contrary, if the fish tank is too small and the filtering power is too strong, it will form a torrent, which is not conducive to the growth of fish.
2. Change water regularly: It is necessary to change water regularly for fish farming. By adding new water into old water, some gas can also be brought in, so as to increase the dissolved oxygen in the water body. It should be noted that water exchange should not be too frequent, and too much frequency is harmful to the water body. At the same time, do not change water violently, pour a large amount of new water directly, which will cause changes in water quality, resulting in stimulation of fish.
3. Planting aquatic plants: Planting aquatic plants is also one of the ways to increase the oxygen content of the water body. Such plants can release oxygen through photosynthesis. However, although it can meet the oxygen requirements of the water body during the day, the oxygen consumption will increase at night, and other ways of oxygenation are needed.
