Acropora placement in tank

So I have had things like montis but I now have a couple frags of acros. I am wondering where in the tank they should be placed? I have a standard 75g tank with a 400w metal halide 14k bulb and 2 54w ATI T5 bulbs. I was thinking mid tank but would like to ask the opinion of more experienced people.
One of the frags is unknown, then I have a purple tort frag and a frogskin acro frag that had fallen in a crack in Carlos's tank so it is more of a brown color right now.
Thanks in advance:)

ya 400 watts you will be more than fine just off that sucker let alone the t5s. I would acclimate all of them start on the sand and go up!

Acro's can handle a lot of light(and need), as long as you acclimate them to it.....purples...tend to lose color and vibrance and are among the SPS corals that need the most light...so after acclimation, I would probably work that purple up to an area with plenty of light to keep its color...or improve it
