I usually check the SG
and if that is the same then I float the bag in the tank or the sump. If it the SG
is close then I just add some tank water if it is off more than .002 I will drip acclimate for a few minutes. The easier corals are much easier than a fish or shrimp to acclimate. Anemones I take my time and drip acclimate them very slowly.
Coral doesn't create a bioload it is what the coral is fed that will create one if it is dumped in the tank. Duncan and sun corals need to be fed. Acans, recordia, and candy cane will benefit from a feeding but I don't go out of my way to spot feed them they usually catch what if floating around the tank. I do have one candy cane that I do feed since it will sting anything near it when it gets hungry and can reach quite a ways.
