Air Pump - Airflow regulator?

[GERGixxer]

Hey folks,
Got myself a Tetra Whisper 10 Air-Pump for my 6gallon tank. I feel that there are still too many bubbles coming out of the airstone creating too much of a current....

Is there some sort of regulator available online/lfs that you know of or do you have other tips how I could regulate the airflow?

Help is much appreciated!

Thanks!

Tie a knot in the tubing and tighten/loosen until the bubbles are where you want them. And it's free. :D

Most aquarium shops will stock a "control valve" which plugs into the airline,This valve has an adjuster which controls the ammount of air that is released through the airline.They are only a small plastic device and are cheap (Vaygirl's method is also a good idea and even cheaper )
