Can a small air pump enrich the water in the whole aquarium with oxygen?

The principle of oxygen pump is to accelerate the flow and circulation of water, so that water and air can be better integrated and the oxygen content in water can be increased.

Usually, the oxygen pump has a switch to adjust the air flow. You can turn on the oxygen tank. If you can't adjust it, you can also buy a bubble tube as long as a fish tank. Remove the original bubble stone from the oxygen pump and replace it with a bubble tube, so that the bubble area will increase. Your fish tank is not big. This oxygen pump should be enough.
