Fish tank does not hit oxygen to have 3 kinds of reasons commonly. The first is that the air inlet is blocked, and the gas can not be discharged from here, in this case, it can be dredged, or a pipe can be replaced. The second is that the position of the pump is too low, and the air pressure is not enough to cause air to enter, which requires adjusting its height. The third situation is that the pump is damaged and repaired or replaced in time.
1. Daily oxygen: It is not necessary to give oxygen to raise fish. If all the fish are small and the breeding density is not high, there is no need to give oxygen to them. If the breeding density is relatively high and the oxygen consumption of the fish is high, an oxygen pump is needed. Daily oxygen time is not too much, 2-4 hours is enough, high temperature season can play more than 2 hours, in addition, if there are aquatic plants in the fish tank, it is best to open another hour in the evening.
2. Open the tank and add oxygen: The tank needs to be opened for the first time for fish farming. At this time, a nitrification system should be established to cultivate nitrifying bacteria. The nitrifying bacteria themselves are aerobic bacteria. They can grow and reproduce in an environment with sufficient oxygen. Therefore, when the tank is opened, explosive oxygen is also needed. At the same time, the light should be turned off.
3. Oxygenation for illness: If the fish is ill, proper oxygenation will help its recovery. At the same time, if medication is needed, some medicines will also reduce the oxygen content in the water body, and oxygen supplementation is needed in time.
