Things You'll Need
- Gang valve
- Measuring tape
- Scissors
- Aquarium air line tubing
- Check valve
Instructions
Attach the base of the gang valve to the outside rim of the aquarium. Most gang valves will have a clip built-in for this purpose.
Measure the length between the aquarium's air pump and the gang valve. Cut a piece of flexible air line tubing to reach between these two features. Ensure you cut enough of the tubing so that it will have some slack.
Attach the air line tubing from the air pump to the inlet pipe of the gang valve. The tubing will slip over these valves.
Cut through the center of the air line tubing between the air pump and the gang valve. Slip a check valve between the halves of tubing, splicing them back together. Ensure the check valve is facing the correct direction so that air will flow from the pump to the gang valve. The check valve will have a directional arrow telling you which way it should go. This feature will protect the pump from water siphoning back into it.
Measure the lengths needed from the gang valve to the air-powered features. Cut the needed lengths in the air line tubing, adding some extra length for slack. Attach the tubing to the outlet pipes of the gang valve and the aquarium features.
Use the gang valve's dials to control how much air flows through each outlet tubing. The more air flowing, the more bubbles it will produce.
