Best way to diffuse CO2 in your water ?

I'm guessing bleach just same as a glass one can't see why not.

Thanks, I thought that might be the case.

It is odd the way the buubles don't head straight for the surface. The diffuser just seems to smoulder in the corner, i can see my Koralla pushing the bubbles around the tank tank though with hardly any bubbles making it to the surface.
