if the fish tank does not have oxygen? If the fish tank does not have oxygen, the fish will not necessarily die. Normally, the water contains a certain amount of oxygen, which allows fish to breathe. If there are not many fish and they are not big, the oxygen content can be increased by changing water or filtering at ordinary times without additional oxygenation. But if the breeding density is very high, or the fish is large, the demand for oxygen is relatively high, which requires oxygen, otherwise it may die due to lack of oxygen.
of oxygenation in fish tanks? 1. Breathing: The primary benefit of oxygenation is that it is conducive to the breathing of fish, because fish live in water and need a certain amount of oxygen. If the dissolved oxygen is too low, it will lead to anoxic floating of fish, and even affect life, so oxygenation is still necessary.
2. Maintain the water quality: The oxygen in the water body is sufficient, which is helpful to maintain the water quality. On the one hand, it can promote the reproduction of nitrifying bacteria, so as to better convert ammonia nitrogen and avoid fish poisoning. On the other hand, it can also inhibit the growth of anaerobic bacteria, which also has a certain purification effect on water.
3. Promote growth: Oxygen can promote metabolism, so when dissolved oxygen is sufficient, the growth rate of fish will also be accelerated. Moreover, fish also need more oxygen in the process of digestion, plus some daily consumption, the benefits of oxygen supply for them are also many.
