Coral acclimation like Saltwater fish acclimation takes time but will reduce your disappointment of watching the coral fade away and die we need to follow proper acclimation to reduce the likely hood of failure.
Handling Corals
Different corals will require different handling techniques for others. For instance, soft corals, polyps, and mushroom corals will normally arrive attached to a small rock, therefore nly handle them by this rock.
Hard corals with large fleshy polyps can be handled by their base, which is the hard exoskeleton. Other hard corals, including SPS corals, should be handled only by the base where it was fragmented, or by the plug or rock it is attached to. A pair of Aqua Gloves is highly recommended in handling all corals, and will reduce the possibility of irritating the coral when handling it.

Acclimating New Corals to Your Lighting System
Among the many species of corals available to the hobbyist, there are many differences in where they grow in nature and the corresponding lighting conditions they need in order to survive. Corals are highly adaptive to different lighting conditions, but some are more sensitive to change than others. It takes time for a coral to acclimate to its new environment, and care must be taken to help the organism adjust. This is especially important with some of the very intense lighting systems, like metal halides and T-5 fluorescents.
Some corals, when not acclimated properly, can actually be "sunburned" by the artificial lighting, which opens the door to infection and possible demise. Place your new coral on the bottom of the aquarium in the substrate until the coral adjusts to the new lighting. A good sign that the coral has adjusted to the new system is when they appear fully expanded and display full coloration. Now the coral can be moved to the desired location. Continue to monitor the coral's response to its new location, and if its coloration and expansion appear to decrease, relocate the coral to a lower position.
Proper Placement of Corals
When determining the final placement for your new coral, research its lighting and water flow requirements, and especially the coral's aggression toward other inhabitants within the aquarium. With all of this in mind, and an open space within the rockwork that affords room for future growth, gently move the coral to its new position. Since the coral may get knocked over by snails, sea urchins or large hermit crabs, we recommend that you use a reef-safe underwater epoxy or Epoxy Putty.
Steps for Coral Acclimation are as follows:
