the fish fish tank power failure, the oxygen pump will stop working, this time to oxygenate the fish, the best way is to change the water. If the feeding density is relatively high, it is not enough to change the water, because the water can only be changed once in a short time, or it is difficult to meet the demand for oxygen, which requires separate tank feeding, after separation, the demand for oxygen will be alleviated, but also to ensure that the water and air can contact.
of oxygenation? 1. Oxygen pump: Oxygen pump is the simplest and most commonly used method of oxygenation, which can meet the needs of fish for oxygen, but will be affected by power outages. Usually, the oxygen pump should be turned on 24 hours a day. If you don't want to turn it on all the time, you can turn it on in stages, two hours in the morning and two hours in the afternoon, which can also avoid hypoxia.
2. Change the water: If there are not many fish and the size is not very big, the oxygen pump will be redundant. As long as the water is changed at ordinary times, the dissolved oxygen in the water body can be increased. Water should not be changed too frequently, otherwise it will stimulate the fish, and even cause some stress reactions, which is very harmful to their health.
3. Raising aquatic plants: In addition to the above two methods, there is another way to increase oxygen, that is, raising some aquatic plants in the fish tank, which can release oxygen through photosynthesis. However, limited to the size of the fish tank, the number of aquatic plants will not be particularly large, so the increase of dissolved oxygen is relatively limited, if there are too many fish, oxygen will still be insufficient.
