Spray bar vs CO2 Loss vs Oxygen Levels

A friend of mines told me that placing a spray bar above the water will result in loss of CO2 levels. However, my setup only allows me to place the spray bar above the water line, so I rotated the water outflow so that it hits the tank wall before entering the water. The results seems fine but now, I am worried about the lack of oxygen.

Do you think the spray bar, in its new position, is creating enough oxygen for my tank?

Some questions . Are you planning on running your tank's water level at half full? Why can't you move your spraybar?
What are the correct dimensions of your tank? And are you running CO2? That information would get you better advise.

As long as you have water moving and it is in contact with the open air, you should be okay. It doesn't look like you have a very high fish load.

Actually that water trickling down wall will actually increase amount of gases, both oxygen and co2 thatís absorbed into water. More air to water contact area as well as providing good high to low water movement.
