Quesetion On Co2

[EliteFishy]

Can I aim the Output line on my external filter so the water comming out of It will push the CO2 bubbles down?

It might work if your output is pointed straight down. Then maybe the bubbles will be trapped inside the current and dissolve. However, it might be hard because the bubbles might come out of the current and just float to the top. Try it, it might just work and other people could do it.
