Mark, make sure your tank has good magnesium, calcium and alk. I only temperature acclimate my acros, then dip them, then into the tank. I use revive and I closely inspect each piece for any sort of bites/bugs/eggs/etc. I do not drip acclimate them. High lighting, strong indirect flow (powerheads will blow the tissue right off coral if placed in strong direct flow)
As Justin said, the biggest concerns when adding acropora are Acropora Eating Flatworms (AEFW) and redbugs. AEFW are the worst bugs so if you see them do what Justin said. Most experienced reefers say quarantine coral because of eggs that may not be killed by dips... but not many people have a QT tank up and running, especially one that can keep sps happy.
What corals are you getting?
