First I float them in the bag in my sump for 15 min or so,
Then, I slowly acclimate the frag to my parameters using a drip (usually for 1-2 hours)
Then once they are ready,
I use Coral Rx for 10 min with 4 cups of fresh tank-water to 1 capful of Coral Rx
then 5 min in a clean bowl of about 3 cups of tank water for a rinse and rest
then 10 min in a Revive dip, again 4 cups of tank water to 1 capful
Followed by another 5 min or so in the bowl of tank water for another rinse and rest
After that, in the tank.
I do this for ALL Corals entering any of my tanks, regardless of where or who it came from, and again before I move them from one of my own tanks to another.
I will also use a xacto blade to scrape any algae I can see or for just general clean up of the frag before the first dip.
This process has been working successfully for me for over a year and the corals usually extend within minutes to hours after the go in the tank or, worst case next morning (as was the case of a stubborn torch that wouldn’t fully extend. I think it was more placement though)
It also is a great excuse to do a water change and still get a benefit from the old water, as your using a fair amount of water from the tank anyways...
The other thing I do is feed Reef Roids immediately after they have been in the tank for about an hour or so. I shut the pumps, mix it thick and direct feed all the corals in the tank including the new ones for around 15 min or so. Even if they are still closed, they typically take some in.
Whether or not it helps, it works for me and I get great growth and big happy puffy corals in a short time after introducing them in the tank.
Hope that helps.
