How do I prepare an Acro to go in the tank?

[MikeP]

I've started to buy some acro colonies. What should I do to 'prep' the coral to go into the tank? Is fresh water dip a common preventative step? If so how do I do it properly? Is there anything else I should do before placing a new acro in the tank? (other than typical acclimation)

Thanks for any info.
