The oxygen pump in the fish tank does not need to be on all the time. Although the oxygen pump has been on for no harm to the fish, but the fish adapted to the high oxygen environment, once the oxygen is reduced due to power outages and other reasons, it is easy to appear some discomfort, or even die. Usually a few hours a day can be opened, as long as the fish in the water to meet the breathing, do not need more oxygen.
1. Daily: If there are not many fish, in fact, there is no need to open the oxygen pump, but for some large fish, it still needs to be opened for 2-4 hours a day. If it is hot or rainy in summer, and the dissolved oxygen in the water body is reduced, it is necessary to open for 2 hours more. In addition, if you raise water plants, you should open them for an hour in the evening.
2. Open the jar: You need to open the jar to raise fish. When you open the jar, you need to cultivate bacteria. Many beneficial bacteria belong to aerobic bacteria, such as nitrifying bacteria. These bacteria must be in an environment with sufficient oxygen to multiply in large quantities. Therefore, you need to be oxygenated all the time at this time. It takes about one day to complete the cultivation of bacteria.
3. Treatment: If the fish is sick, the content of microorganisms in the water will often increase, which will lead to insufficient oxygen in the water. At the same time, the tablets put in during the treatment will also consume oxygen. Therefore, during the treatment of the fish, it is necessary to use an oxygen pump to oxygenate it.
