CO2 Diffuser next to the outlet?

Has anyone ever placed their in-tank diffuser next to the external filter outlet? I just got back to using a diffuser (reactor broke) and noticed how much CO2 is seemingly lost just by bubbles going straight to the surface. My thoughts are that if you were to put the diffuser next to the outlet, gas would pass through the filter as sort of a makeshift reactor that would A) reduce bubbles lost at the surface and B) reduce the sodawater look of the water.

Thoughts? Experience?

I tried of my fluval Flex 15. Since the diffuser is on the glass of the aquarium, I needed to aim the outlet nozzle toward the glass so the water could reach the bubbles. I didn't like it because some places had lof of flow and some not enough. It was difficult to have a good flow everywhere in the aquarium.

I prefer to place it next to the inlet, so the remaining floating bubbles could be sucked in the filter.

Be sure to place the drop checker to the opposite side.

Be careful if you are doing this; with a high enough injection rate, it is possible to air lock your filter (canister filters might be more prone to this).
