Would This Method Of Diffusing Work?

[ziggyboy]

I'm thinking of putting my DIY CO2 tubing just below my canister filter's inlet tube. This way the filter would suck the CO2 in and hopefully diffuse it in the water while traveling across the various tunnels of the filter. How effective would this be?

CO2 direct into filter inlet works very well in my experience. Cheap, simple, low-maintenance and effective.
