2.5 Mini-Bow / Aqua Expert 600 Air pump pumps to much air

The Aqua Expert 600 that came with my 2.5 Mini- bow seems to pump to much air for my Betta's liking.
Any suggestions on what to do?
Is there a air pump that would pump less air and work for the 2.5 gallon (Quite too..lol)?? Or something i can do to reduce flow??

They have smaller pumps.." whispers" are my favorite.
You can also reduce flow by putting a small
clamp on your air line tubing...but getting a whisper pump may be your best bet.

Put in another valve, and bleed off some of the excess air pressure. Try to make sure the bleed valve is above the water level. In fact, the pump should be too. That way if the power goes off you will not start an accidental syphon. I've seen it happen. If you can't put the pump above the water level, use a check (one way) valve (they're cheap), and put the bleed valve between the pump and check valve.
