what do you do if you introduce a new coral?

If you have leds and have them turned up high for sps corals, I'd suggest you either put new corals as deep in the water as you can and then move them up to their final home in a couple of steps so they get use to the light. The alternative is to find or create a shadow area like a rock overhang or something to block some of the light and move the coral into the light gradually.
But if your lights aren't turned up as bright as the corals can tolerate, then acclimating is much less of an issue. The basic acclimate it deep in the tank and move it up over time, say 1 to 3 moves over 1 to 3 weeks. This works for MH and t5 lighting as well, but more often than not, they aren't at the upper limit of the coral's ability to tolerate. Leds can get too bright if you aren't careful.
