'Burping' filter!?

Been trying to increase the amount and effiency of Co2 into my tank.
(Changed the scape and brown algae starting to appear, and more worryingly, beard algae)

I have one of the black circular Fluvial diffusers that were so highly recomeded on here .
It seems to be working well and making tiny bubbles, which flow directly into the inlet of my external eheim.

However, when I run about 4 - 6 bps or more, the filter starts to burp out bubbles. not all the time; Maybe every 15 mins or so.

So I'm guessing the absorbtion isn't keeping up with the output of the diffuser?
Is there anything I can do to help?
Recently saw a beautiful tank in LFS and they just used one of those bubble ladders!

I now bring my Co2 supply on 2 hours before lights and just cannot get anything more than dark green DC.

Thanks for the help
Andrew
