9011 With a CO2 Scubber

I recently upgraded to a 9011 skimmer (love it), but I'm having a challenge figuring out how to connect it to my CO2 scrubber. The CO2 scrubber is just a canister that sits outside of my cabinet, connected by a section of flexible air line. On prior skimmers, I simply connected it to the air intake port.

I connected the intake tubing to what I *believe* is the air port (large port just right of the adjustment screw), but it seems to draw very little (if any) air. I also covered the ozone port thinking this might be an air source to no avail. It sounds as if it's drawing air from within the skimmer itself, instead of from the air port. It's running in a sump at 9.5" of water (constant compliments of an Osmocontroller) without the extension kit. I've tried all the air setting combinations I could think of.

The skimmer performing very well otherwise, I just need to find a way to get it to draw air from outside the cabinet. Am I missing something? Any advice is greatly appreciated.

Thanks much!
 
The air intake on the comline skimmers is a bit complicated, it uses the chamber under the cup as a sort of mute to silence the air intake. On the backside of the blue screw under the cup is the actual air intake, this is where there is actual suction. The large nipple is where air comes in, the small nipple is for injecting ozone. If you plug both the air will be taken in under the cup and some water will be sucked in as well by the vacuum. To add ozone or inject fresh air into the chamber under the cup and airpump will be needed. It doesn't need to be anything fancy, a 300l/hr air pump should meet the full demand of the skimmer, I personally would recommend Schego air pumps or the Corallife Luft, neither is really silent but both air pumps that have been around for ever and you can rebuilt and get replacement air filters for so they are proven durable.
 
Thanks Roger - I ordered the Schego M2K3. Should I use the Ozone port, or the larger air intake port? - It *appears* the larger port would be preferable for moving that much air.
 
I would use the ozone port, you are pumping in under pressure so the small port should do the job, the M2K3 is adjustable as I recall so you should be able to fine tune it.
