Hi Brett,

Regarding your inlet and outlet locations, Your only option is to have them on the back wall, given where your overflow is.
What I like about the tidal flow setup is that it almost completely eliminates dead spots where detritus can accumulate.
If you can locate your sump return line(s) and your rock layout, it might become obvious where exactly your plumbing holes should go.
