What size pipe are you using? 1.5" or 2" hopefully
The best way to plumb a system is in an "S" shape. Go up to the top row and then work your way down in a continuous line. use valves on each tank. leave a valve at the bottom to return to the sump in case you wanna relieve pressure or empty the line. Don't kill yourself using 45's if you only have a few corners to do, not that big of a deal.
Any way you could post up a drawing of what youare talking about. I am pretty sure I understand, but I'm kind of a visual guy. LOL
EDIT: Sadly enough, I'm using 1"
