Almost there, but...

I have a very similar set up. I use a mag 12 and have put in ball valves on both lines so i can adjust the flow down just a little bit. It took a very little bit of tuning at first but works great. As for the spray bar i put a bunch of "t"'s along the pipe and then caps on the t's with different sized holes and configurations to suit the needed flows in different areas of the tank. Go for it!
