Parts Required
- Two pieces of fiberglass or plastic screen. (Do not use any type of metal screen)
- One piece of clear plastic pipe. (I used the tube from an old gravel vacuum for this one)
- Two P.V.C. pipe couplings. (These must fit over the end of the clear pipe)
- A section of airline.
- An airline gang valve. (You can get one of these at your local petstore)

Step 1
Wrap one of the pieces of fiberglass screen over one end of the clear pipe and cap it with one of the PVC pipe couplings.

Step 2
Wrap and cap the other end of the pipe same as step #1.

Step 3
Trim away excess screen material. You can use a razor blade to trim it up after the scissors if you want.

Step 4
Cut an "X" just big enough to slide airline into one end of the screen.

Step 5
Slide one end of the airline into the "X".

Step 6
Attach the gang valve and air pump as shown .
