I have a 90 Reef Ready tank set up as FowLR with Herbie method as plumbing. I have most of my LR in front of the overflow to kinda hide it. The right side of the tank is more open, but some LR. My question is should I move the return to the right side of the tank so flow goes towards the wall of LR to keep stuff from settling on it? I am afraid of the water being too loud going in the overflow if I move it. The surface is calm at the overflow as it currently setup. Or should I get a powehead behind the LR wall?
