Eheim 2213 and Co2

Hi all,

I'm running my pressurized co2 line directly into my Eheim 2213 canister filter and using the filter to absorb the co2 bubbles like many here do.

With that said, however, it doesn't seem to be working!

The bubbles go in just fine, they just never come out!
After waiting awhile you can rock the canister filter and then boom you get a 30 second bubble chopping sound and a whole mess of bubbles come pouring out.

What gives? Is that supposed to happen? I'd always figured that they would be chopped as they went in.

Did you try using a CO2 reactor inline? I believe it is best to make sure the CO2 is fully dissolved before it gets to the filter to avoid the problem you noted.
