I always inject them in the tank. You can inject a couple ounces of vinegar per 100 day per day without causing any negative reactions and you can inject plenty of majanos per ouch of vinegar. If you want to take the rock out of the tank, soft corals are usually fine out of the water for several minutes, SPS and LPS for a couple minutes max, and zoos can go much longer, but if too much vinegar gets directly on the coral, you might run into problems, which is another reason why you inject them in the tank (or at least a bucket full of salt water) to keep the vinegar from sitting on the outside tissue of a coral.
