I've seen the spray bars run down the side of tanks and not just along the top. It looks as though you're using a Rena XP filter? They have a ball valve included. No matter how you mount your spray bar you can put the ball valve on and slow down the flow if need be. Not sure if that helps?

This will provide the surface agitation you need to keep the gas exchange level constant. It will also allow for a nice even level of water movement throughout the tank.
