Tetra whispers are the quietest I've found, it's all I'll use now. I leave it on 24/7 in my room and never ever hear it, sleep with it on and everything, not a sound.
Patrice said:I have a tetra whispers to. Seem ok, but get one size smaller from what you need and a better check valve. Example : if you have a 30g get a 20 tetra whispers. Thank for the thank.

Air pump only add air in aquarium because its doing wave on top of aquarium.
