? If the fish tank is too full, will it lack oxygen. The content of water does not affect the content of oxygen, but leaving a certain layer of air allows water and air to contact, which also allows the dissolved oxygen in the water to increase appropriately. Usually, if the fish is relatively small, and the feeding density is not large, there is no need for oxygenation and no lack of oxygen, but there are more fish, oxygenation equipment is needed to supplement oxygen to the fish.
the fish tank 1. Change the water: The simplest way to oxygenate the fish tank is to change the water. Because the old water is pumped out and the new water is injected, the dissolved oxygen of the new water is higher than that of the old water, so the oxygen content will increase. In addition, in the process of changing water, some air will be brought into the water, thus increasing the dissolved oxygen.
2. Oxygen pump: The usual way of oxygenation is the oxygen pump, which pumps air into the water through the motor. Although it is not pure oxygen, it can also increase the content of dissolved oxygen in the water body. Moreover, pure oxygen may be saturated, and even cause bubble disease in fish, but air will not cause this problem.
3. Aquatic plants: The aquatic plants in the fish tank can carry out photosynthesis and release a small amount of oxygen at this time. However, the ability of photosynthesis is limited. It is unrealistic to expect it to satisfy the fish's breathing. Moreover, the plants also consume oxygen at night and need other oxygenation methods.
