I have a canister filter. If it is strong enough, could I modify the impeller to be a needle wheel and then simply run the CO2 hose directly into the filter intake in the tank (just put a hole in the prefilter and run it thru)?

I do exactly that, except I haven't bothered to modify the impeller of my canister filter. I get complete dissolution without any buildup of CO2 in my canister. It's like an inline PVC reactor except that it happens to have filter media in it. It's worked well for me, so I've never wanted anything more complicated or involved. Simple is good, right?
