Depends on lighting type/coverage. Low par but a good even spread of light a coral will do much better than low par from puck style LEDs and uneven coverage. That said I wouldn’t recommend any acro be kept at those levels for an extended amount of time.

Also, the term “deep water” for smooth skins is a myth. Any of the common smooth skins in the trade are growing at the same depths as majority of acros and would do best in 300-500 par ranges as will others
