Is it ok to just put the CO2 tube into the inlet of my canster filter? I

simple route.

Yes. I have three planted aquariums where the CO2 tubes bubble directly
into all canister filter intakes. The CO2 is completely dissolved. The
only problem that I encountered once was when one of the filters had its
flow reduced because of lack of cleaning. The CO2 took longer to dissolve
and finally caused an air block. This hasn't happened again though.

If there was an adapter that fits in between the hose, say the outflow hose
then that would avoid any chances of an air block occurring? You may not get
as good as diffusion but you wouldn't ever have to worry about your pump
....all it would have to be is a plastic tube and a fitting for the CO2
hose...
does anyone know if such a device exists
