, if the fish tank does not have the oxygen equipment, does not bubble is also the very normal matter. If there is oxygenation equipment but no bubbles, it means that there is something wrong with the equipment. It may be that the negative pressure of the oxygen machine is insufficient, or that the air outlet is blocked, or that it is burned out because of frequent opening, or that the small impeller is stuck. There are different ways to deal with different situations.
if the oxygen pump does not bubble? 1. Raise the position: If the oxygen pump does not bubble, it is most likely that the water pressure is high and the air pressure is high. The power provided by the oxygen pump is not enough to pump the gas into the water. In this case, it is necessary to increase the height of the oxygen pump appropriately, so that the air pressure will increase until the air outlet can bubble. And then fix its position.
2. Adjust the tube: If the tube of the oxygen pump is too long, bubbles may not come out. In this case, it needs to be shortened. At the same time, pay attention to the position of the gas head, do not put it too deep. In addition, the pipe should not be bent, otherwise it will not be able to vent.
3. Clean the pump body: If the inside of the oxygen pump is blocked, it will also cause it not to bubble. This situation is also relatively easy to solve, need to take it apart and clean it, clean up the blockage, reinstall it and continue to vent.
