? It's better to keep the oxygen pump on all the time, so as to ensure that the oxygen is sufficient and there will be no hypoxia. If there are not many fish and the lack of oxygen is not serious, it can also be oxygenated in stages, four hours a day, usually two hours in the morning, two hours in the afternoon, and two hours in the evening if there are aquatic plants. In addition, in summer and rainy weather, the opening time should be extended.
? 1. Breathing: The primary benefit of oxygen is to increase the dissolved oxygen in the water, which allows fish to breathe better. If the oxygen in the water is insufficient, the fish will have the performance of floating head, and in serious cases, it will affect its survival. Therefore, in order to meet the demand for dissolved oxygen, the oxygen pump should be turned on for 24 hours.
2. Maintain water quality: Sufficient oxygen in water can inhibit the reproduction of anaerobic bacteria on the one hand, and accelerate the establishment of nitrification system on the other hand. After the digestive system is established, the water quality can be maintained, thus reducing the content of ammonia nitrogen in the water and avoiding the poisoning of fish, which is of great help to their health.
3. Accelerate metabolism: The metabolism of fish is often related to the oxygen content in the water. When the oxygen is sufficient, its metabolic rate is faster, which can not only promote growth, but also accelerate the discharge of harmful substances, thus ensuring the health of fish.
