I agree with everthing you said and that's how my tank is setup.
I have a 90 gallon setup with a 30 gallon sump/fuge with all the equipment hidden below the tank. I love it!
But for this 75 gallon I am trying to make as dummy proof as possible.
I'm even going as simple as teklight 6x t5 for lighting... No MH
for this setup!
