If you are adding CO2 to the inlet of a powerhead you will get CO2 mist out of the powerhead. That mist should be directed so it hits as many plants as possible, preferably low in the tank. I think it is a good idea to have a little ripple on the water surface, too, but I do that with the canister filter outlet. I have that outlet near the top and angled so the surface is just slightly rippled.
