Can I turn off the oxygen bottle at night? When do you need oxygenation?

The oxygen pump can be turned off at night. Usually, only when the breeding density is high or it is hot and rainy, oxygen explosion is needed all day, and the oxygen pump does not have to be turned on all the time at other times. Usually, the oxygen pump only needs to be turned on when the gas cylinder is opened to cultivate bacteria, so as to promote the reproduction of nitrifying bacteria. In daily farming, 2-4 hours a day is enough. But if you are sick, you should always take oxygen to avoid death due to lack of oxygen.

1. Can you turn off the oxygen cylinder at night? The oxygen pump can be turned off at night. Whether to turn on the oxygen pump at night mainly depends on the culture density in the fish tank. If there are too many fish and the oxygen consumption is high, they will be opened at night. In addition, in hot and rainy weather and when the fish is sick, it also needs 24 hours of oxygen explosion, otherwise it is prone to hypoxia and the fish is easy to float.

Second, when do you need aeration 1, culture bacteria and aeration: the so-called culture bacteria are nitrifying bacteria and aerobic bacteria, which need sufficient oxygen in the process of growth and reproduction. Nitrifying bacteria are indispensable beneficial bacteria in fish tanks. The residual bait fish in water will be decomposed by microorganisms to produce ammonia nitrogen, which is not good for fish health. Nitrifying bacteria can transform these ammonia nitrogen into nitrate and become nutrients for aquatic plants.

2. Daily oxygenation: In order to ensure sufficient oxygen in the fish, the aquarium should be oxygenated for a period of time every day, which is about 2-4 hours under normal circumstances. If it is summer or rainy weather, the air pressure is relatively low and needs to be extended to 4-6 hours. If there are aquatic plants in the tank, it is best to inject oxygen for 1-2 hours at night to avoid consuming too much oxygen when breathing at night.

3. Oxygenation during illness: If the fish is sick, it is necessary to change the water to raise the temperature and reduce the salt during the treatment. The increase in temperature will reduce the dissolved oxygen in the water. In addition, if medication is used, it will also consume oxygen in water. At this time, there will be an oxygen explosion. The oxygen explosion lasted until the end of treatment, and the fish was healthy.
