The trachea of fish tank oxygen pump is very long.

The solution to the problem of long air tube of fish tank air pump is as follows:

1. Cut off the trachea: If the length of the trachea exceeds the actual needs, you can cut off the trachea to a suitable length with scissors, and then connect the trachea to the oxygen pump and gas stone.

2. Install an intermediate joint: If the length of the trachea is appropriate, but it needs to be connected to a far place, an intermediate joint can be installed to divide the trachea into two sections to reduce the resistance of the trachea.

3. Replace the air pump: If the length of the trachea is too long, which has affected the working efficiency of the oxygen pump, you can consider replacing the oxygen pump with higher power, or placing the oxygen pump near the fish tank to reduce the length of the trachea.
