Diffuser Fitting?

[Tiger Tiger]

Hi
I would like to fit a diffuser on the end of my Fluvall 4+. Has anyone done this and can they point me towards the right one?

Thanks

is that to make bubbles??
i dont think you can with the 4+ i thinks its only poss on the 1 the way to do it is put the outlet at the surface to aggitate the surface...

i`ll shut up cos that could be the wrong answer anyway

i have it on my 2 plus. there is a hole in the top of the outlet. i have it an inch below the surface and have 2 inches of airline pushed into it so it looks like a snorkel! so it puts air into the tank. so no extorsionate airpmp needed really. HTH
