fish oxygen machine does not have to always open. Usually, oxygen is enough to open for a period of time every day, if oxygen saturation, it is easy to cause fish to suffer from bubble disease, while adapting to the high oxygen environment of fish, once the oxygen is reduced, it will be more troublesome to adapt, and may even die directly, so it is better not to keep the oxygen machine open all the 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, it is not necessary to give oxygen to them. If the breeding density is relatively high and the oxygen consumption of the fish is high, it is necessary to use an oxygen pump. 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 a fish is ill, proper oxygenation is helpful for 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.
