Is it ok to just put the CO2 tube into the inlet of my canster filter? I
bought some crazy thing called the 'Aqua Medic Membrane Reactor". It worked
for a while (just discharging large CO@ bubbles into the water), now the

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.
