Working Hagen CO2 video??

I just purchased the Hagen CO2 system and set it up. It has been 16 hrs. now and I see a couple bubbles in the diffuser but no action? Is there anywhere I can see a vid on how this thing is actually suppose to work? Do the bubbles continually rise up the diffuser or are they really slow moving?? :hang:

ok, thx. I put the ladder almost to the bottom of the tank, so I think it will take awhile to get the pressure down there. I do see the bubbles starting to form more now. "Hurry up and wait"... :dive:
