Sounds like the flow is great as is. I agree that you should try to not have a pump on that front pane. It makes it so much cleaner. I would leave the lights off unless you are going to add a CUC to keep the algae biomass down. Also conserves a little energy.
I am going to do whatever I can to not have a pump on the front pane. I am even thinking of little excuses ( 90% of the power heads out there do not have a long enough power cord between the pump and the controllers to reach the front without mounting the controller of tank side of the wall. Currently everything routes through the wall and I want to keep it that way)
