Co2 diffuser making high pitch noise..?

[Smcoyle87]

I have the Hagen yeast co2 system and i just moved it from one of my planted tanks to a brand new one i just set up.
Its been up for about 2 weeks and ive noticed a very high pitched noise coming from something in or around the set up.
I think its the diffuser because ive unplugged everything and it still happens. The diffuser is the only thing that doesn't use electricity.
Anyone have any thoughts?? Haha kinda weird

I hear it on mine when co2 is really coming out... Mine comes out in spurts and makes a noise when it does.

Can't think of how to silence it. I do use an air stone on it BTW.

Could this be a leak you're hearing?
What kind of diffuser do you have on it?

IME that kind of diffuser will make a little noise from all the little bubbles its making bubbling. Make since? Haha

Ok, i just didn't know if it was normal to actually hear the co2 working ha. Seems like it would be silent to me.
