Flow? Depends - no certanties. In my setup the returns are at the four corners on the back wall. I had the tops pointing along the surface & the lower returns pointing off the wall & forward. Ended up with some dead spots behind the rocks (got filthy back there). Pointed the upper two down along the back wall & added the Tunze = nothing stays to settle.
Same here, only run about 700 through the sump - most of the flow is in the tank.

O.K., that makes sense now. What do you think about setting up a dual locline out of each of the rear upper corner return holes, pointing one locline toward the front, the other split locline back behind the rocks? I was hoping to avoid any powerheads in the tank...
