I have a Rhinox 2000 glass diffuser on my pressurized co2. I get a lot of bubbles built up at the water surface.

Does this mean I am not getting good absorption ? I have an old whisper hob overflow type filer. I had another smaller one so I added that one to help break up the bubbles.

I put the Rhinox directly under the inlet tube of the smaller filter to help with dissolving. Would the co2 be release at the surface because of the filter type?

I will try to post some pics later.
