Quiet Air Pump

[Joeyg2100]

What are the quietest air pumps out there. I have one for my 55 gallson that is running an undergravel filter. But this thing is loud. I am willing to spend some money on a good one, so just give me all your ideas.

All air pumps make some noise, I have about 4 different brands in a box, none of them are quiet.

If you are using the air to run ugf try a couple of powerheads on the up tubes. This is much quieter than air, provides more flow for better filtration, and they cost as much as a cheap air pump.

After being thoroughly unimpressed with Rena air pumps, I found TetraTec to be considerably quieter.

Just my 0.02$!

I have eheim two pipe outlet which isnt to bad, it depends on the surface its sitting on I did have it hanging on a hook for a while but moved it because it didnt look good there but on a solid shelf or in a cupboard they can act like a speaker and magnify the sound.
