So I picked up the glass/ceramic diffusor sold by Dr Fosters and Smith, and its definitely attractive, but emits a white-noise-like sound when diffusing CO2. This is definitely the diffusor and not a leak before that point. Is this simply the reality of forcing gas through ceramic, or are other ceramic/glass diffusors quiet? (Or, at least close to quiet?) Hows yours in terms of noise?
Thanks.
Thanks.
