fish turns over without oxygen, it will take several hours to recover. If the fish turns over without oxygen for too long, it will not even recover. The reason for hypoxia is that the feeding density is too high, the consumption of oxygen by fish is relatively high, or because the temperature is too high, the rise of temperature will lead to the decrease of dissolved oxygen in the water body, and the fish will also be anoxic. If you want to solve the problem, you'd better prepare an oxygen pump for oxygenation.
1, equipment oxygenation: for hypoxia, the best solution is to use oxygen pump oxygenation. According to the size of the fish tank, we should choose the equipment with appropriate power. If the power is too low, it will not have the effect of oxygenation, but if it is too high, it will change the overall water flow and have a certain impact on filtration. In addition, this kind of equipment is best opened 24 hours, and it is still risky to open it in stages.
2. Drug oxygenation: Drug oxygenation is mainly used for fish farming in fish ponds. Commonly used oxygenation tablets can increase oxygen, but this kind of thing can only be used for emergency, and can not be used to supplement oxygen for a long time. In addition, it should be noted that oxygen-increasing tablets should also pay attention to the dosage, so as to avoid excessive medication causing certain harm to fish.
3. Change water for oxygenation: If the feeding density is not very high, normal change of water can play the role of oxygenation. Because in the process of changing water, new water will bring in a certain amount of air, thus improving the overall dissolved oxygen. However, it should be noted that in order to supplement oxygen, the fish tank should not be changed frequently, so that the fish will be stimulated, and even trigger a stress response.
