Marineland C360 Canister Filter

I have 2 of these on my 75 FOWLR. I'm having a problem with both constantly blowing out bursts of micro bubbles every minute or so. I can shake the canister back and forth a few times and the build up of bubbles comes out the return. But after awhile it starts again. I've made sure all connections are tight and all O-rings are good.
Is it possible that my oxygen saturation is so high that it builds up in the canister? Or maybe it's do to the biological process within the canister? I can't understand it unless it's a design flaw since it's a new product from Marineland.
I can't find a number for marineland either. If someone has a number for them I'd like to have it or any other suggestions. Anyone else have one of these canisters?

I have a Fluval canister, and mine does the same thing. I don't have any problem with it, but I'm interested in knowing where the air is coming from as well.

I have a fluval 405 and mine did the same thing.I had to tighten them with a pair of channel lock pliers hand tight is not good enough for them.
