? If the oxygen in the water is insufficient, the fish will die in 5-10 minutes. If the content is not very low, it may last longer. Fish live in the water, but they also need to breathe. They can absorb oxygen in the water through their gills, so if the dissolved oxygen in the water is insufficient, it will also lead to the death of fish. If you raise fewer fish, you can oxygenate them by changing water, and if you raise more, you must use an oxygen pump.
are the methods of oxygenation 1, oxygen pump: oxygen pump is the most commonly used way of oxygenation, home fish with it can completely avoid the occurrence of hypoxia. Generally, the oxygen pump should be opened all day, but if the lack of oxygen is not particularly serious, it is also feasible to open it in stages. It can be opened for two hours in the morning and two hours in the afternoon. If it is summer or rainy weather, the time for opening the oxygen pump will be increased.
2. Oxygenation tablet: Oxygenation tablet is also a commonly used oxygenation method, but it is rarely needed for family fish farming. It is mainly used in aquaculture and is an emergency oxygenation method for fish ponds. It should be noted that oxygenation tablets may have some side effects, such as increasing the alkalinity of the water body, or affecting the growth of algae in the water.
3. Aquatic plants: Aquatic plants can increase the oxygen in the water body through photosynthesis, so some aquatic plants can be planted in the fish tank. However, it should be noted that fish consume much more oxygen than they provide, and respiration in the absence of light will also lead to increased oxygen consumption, so although there is an oxygenation effect, it still needs to be supplemented by other means.
