Revive is good, when properly used.
& i also think u dipped too long. After 1-2 hour slow acclimation, I dip 1-3 min using a weak powerhead while gently shaking the coral while visually inspecting for red bugs, white worms, brown worms, crabs, etc. then rinsed off in another bucket of tank water.
The stress could be from changes in parameters as well. To be extra safe test pH, alk, ca from the water in the bag. If the numbers are very different the acclimation will be longer (4-6hrs, even overnight)
