I recently replaced my cheap chinese diffuser with one of these because the bubbles seemed quite big, there doesn't really to be a significant difference though. I'm curious as to whether it's worth upgrading to a more expensive one (I'm looking at the TMC or Do!Aqua ones, are they basically all the same or is there a genuine difference in quality in the ceramic discs? (I really would prefer a glass one)
(I've currently got one of those Bouyo inline diffusers but that's throwing out some huge bubbles that shoot straight out of my lily pipe to the water surface.)
