If you want the quick method that has always worked for me, I float the bag for about 20 min. , then open poor into a container, every 5 to 10 min I add about 1/2 to 3/4 cup of water from the tank until I have trippled the water level. I have been doing this for about 3 years. The last time I lost an sps was when the movers cracked my 120 gallon tank and I lots 75% of my corals because I had to put them in a rubber made for a week till i got a new tank. P.S. don't us two men and a truck for moving stuff in madison.
