Hi all,

I'm using an Eheim diffuser (air stone or CO2 diffuser) and whilst the bubbles are as tiny as can be it has a high pitched squeel to it

When used as an airstone they are quite noisy, but with CO2 they just scream!

Are all of the CO2 diffusers teh same (ie the ceramic disc type) or is it just this one?

Thanks :thumb:

I did have a similar issue when teh CO2 diffuser was near the intake, but I have moved it. Despite my thinking the tiny bubbles weren't making the filter they must have been, as after a day it was FULL of CO2 :roll:

The bubbles from the diffuser are so small anyway that they don't break the surface and are getting driven around the tank by teh filter outlet. I'm happy I'm getting good diffusion, I just wish it didn't have this high pitched whistle :?
