My aquarium oxygen pump does not add oxygen. What's the matter?
The air inlet is clogged. Take a small needle and wear it
The water is pressure, the water pump is low, the flow of the air outlet can not bring the air out of the cylinder. The pump is equipped with high energy to solve the problem.
That depends on whether the oxygen pump is still working, and if you are still working, the other is still running down, then it proves that your pump needs a change of position, and that the plastic pipe outside the link needs to be inserted again. If the oxygen pump does not work, you need to take down and clean the pump body, if not work, may be the oxygen pump motor burned.
