be raised

without an oxygen pump? Fish can also be raised without an oxygen pump. You can choose to raise ornamental fish species such as betta, which do not need so much dissolved oxygen. When feeding, control the breeding density, not too high, so that even if they are not given oxygen, they can survive normally.

2. What to do

if there is no oxygen pump for fish farming? 1. Increase the frequency of water change: If there is no oxygen pump for fish farming, you can reduce the pollution rate of water and increase the dissolved oxygen in the water in the tank by increasing the frequency of water change. When the water is changed, the oxygen in the air will enter the water in the fish tank. Moreover, the dissolved oxygen in new water is generally higher than that in old water. Therefore, the concentration of dissolved oxygen in the fish tank can be increased by properly increasing the frequency of water change.

2. Plant some aquatic plants: If there is no oxygen pump for fish farming, you can also plant a proper amount of aquatic plants in the tank, so that they can use photosynthesis to synthesize part of the oxygen and provide it to the fish. It should be noted that fish tanks with aquatic plants need to be placed in a slightly better light area so that they can carry out photosynthesis. If the light is insufficient, they can not synthesize oxygen, and there is no way to increase the dissolved oxygen in the cylinder.

3. Reduce the feeding density: properly reduce the feeding density and reduce the number of fish in the fish tank, which can reduce the consumption of oxygen in the water. This can also increase the amount of oxygen in the cylinder.
