Propeller Pump Placement in 55G (1 Viewer)

[Elixibren]

Where is the best placement and angle for 2x 800 GPH Propeller pumps in my 55G if I have just the main rockwork in the middle of the tank to get good circulation? I can't seem to physics this very well. I tried my best to google this but I have been unable to find any documentation on best water circulation practices in a 55G tank

I would place one on each end, and angle them so you create a clockwise or counter-clockwise circulation around your rocks. I have two set up that way in mine, and have another on a wave timer to create a bit of turbulence and counterflow.
