I'm trying to decide where to best place my powerheads but I'm not sure what's ideal for FOWLR
4x2x2 - I will describe this looking from above the aquarium using cardinal directions.
NW corner = filter output =~ 1000gph. It splits and aims S and E up towards top of water @ 45* angle.
NE corner = Seio 820 aiming W @ 30* angle down
SE corner = Seio 820 aiming W and up @ 45* angle to surface
I don't know where to position or aim these seios. I will have 100+ lbs of liverock when it arrives. Should I aim them all up at the surface or aim some at the live rock?? thanks!
