acclimatize coral?

[Haloreef]

I have never acclimated an SPS coral. I soak them in a container containing whatever water was in the bag and enough water out of the display to equal a gallon and them add Coral RX at a little over the recomended dose and let soak for 15 minutes or so. I have forgotten corals for almost as long as a half hour and they have survived.
I then remove from the dip, rinse with tank water, and put them some where that the slime gets carried away by the current, and then put them in the place I have selectrd and keep an eye on them for the next week or so.
Works for me.
I figure that what ever my tank levels are at, they have to be better than the dip.
