no, i actually kept a rather heavy sps system on my last tank. This new tank is too young for them, just yet.
But even with sensitive SPS, all i ever did take the corals out the bag and put them into a dip bucket with tank water, heavy dip in bayer (I like it milky white) followed by 2 rinse baths of fresh tank water then into the tank.
Never lost a coral from just moving it to the tank. now some corals hate bayer, so they get irritated, but they dont die.
Giving the coral an hour acclimation wont make any difference in it getting used to the water difference. a 7 to 10 dkh shift is still there and that hour wont make a difference IMO/IME.
Personally i find it better to get them into a cycled tank quicker than later especially if they have been shipped and have that added stress.
But everyones tank and experiences are different so i can only comment to mine.
