Power head Placement help

[Kenkee]

Hi guys I have two Nero 5s that I need help deciding the placement of, this is my first saltwater tank and I plan to add corals down the line, also any recommended flow strength or schedules would be appreciated.

Looks good, one on both sides, offset.
I randomize flow as much as possible.

Hey what did you end up going with?

I'm currently thinking about power head placement. My tank has a black back wall and I would like to put my power heads on that wall, purely for aesthetics..but I'm not sure if this is a good idea..
