I use internal reactors because they dissolve 100% of the CO2 and don’t have to sit in the tank. Just buy one or make one for 20$ or 10$ respectively.
Glass diffusers aren’t that bad, but quite a bit of CO2 does make it to the surface without being completely dissolved.
CO2 reactors are attached to a canister’s filter return pipe (pipe that sends water back to the tank). Just cut the tube into 2 pieces and put the reactor between the two tubes.
