Injecting Co2 directly into Fluval FX canister filter?

[denogginizer]

Has anyone tried this?
My concern is that the Fluval does it's "air purge" thing once in a while and I'm concerned that it would overdose the aquarium with Co2.
Thanks!

You don't want CO2 going into a filter because it will adversely affect the beneficial filter bacteria.

I would recommend getting an in-line diffuser for your filter outlet, it can be spliced directly into the filter outlet house and will blow the CO2 everywhere giving you good distribution.

I currently have it right under the outlet. I've had a hard time finding an inline diffuser for the big FX6 hoses.
I think ID is one inch.
