Anyone used the actual Eheim Oxygen diffusers?

Hi Taksan,

I bought one, but never got around to using it and then gave it to Ben. I'm sure he will be able to give you an opinion about them, from memory it worked well for him. From what I have read around the forums they work a treat.

Not much help really ... Sorry !

Cheers,

Dee. :)

My Sacem Marathons came with the same thing... not bad at all IMO
