Flow questions

[reefertown]

hi all,

I’m working on a 96” x 48” x 16” tall grow out system.

It’s three-quarter inch glass and there is one internal box overflow on the peninsula side.

My question is regarding flow. I’m considering a closed loop system but I’m unsure of layout. I’m also open to doing powerheads only. What are your thoughts, and how would you set it up? If it was your tank?

I'd keep it as simple as possible but with redundancy. So I'd use two smaller return pumps instead of one large one and several powerheads.
