How can the oxygen pump in the tank be out of oxygen, or pumping water, but without oxygen?
You are using a three in one pump! It has two outlets, through a filter, another boost to the water cycle, with a pipe interface at the outlet, the use of negative pressure high speed water flow will generate air suction and blowing in order to achieve the effect of aerobics, there is no bubble flow for the following reasons: 1 the pump placed too deep, 2 outlet dirt, especially is the root of the intake pipe, 3 tracheal blockage.
See your pump is still not vibration, don't move it at electric power is not over, if you see in trachea have folded gas barrier. If these two conditions are not predict is retiring. No bubble pump to remove the cleaning, if it is already too long if you use a small screwdriver to vent hole at large point on the line.
There's a good chance you're out of gas. It's blocked up. Just get a wire through it......
