co2 injection

Nothing new to you guys, but brand new to me. What do you think? I cut a hole in an old aquarium salt container, stuck a powerhead through, and bubbled co2 up from the bottom. Super simple.

I'll post this again for you to think a little about. If you have the powerhead pointing downward down the tube, it will increase flow within your tank and also spread the co2. People have done "tests" showing microbubbles that stick to plant leaves are much more effective at transmitting co2.

This one is okay, but how does the water escape?

i put my CO2 tube and air stone into the intake of my power head, and get really tiny bubbles that get shot all over the tank.
