I have an encrusting gorgonia coral that is on a rather large sized rock. I just moved it to a different spot a couple weeks ago and it seemed to love it. there is a k4 pointed directly at it but about 8 inches away so it does not get blasted with flow, but it does get flow. Now about 4 of the 12 inches of this strip of coral has brown jelly on it and im wondering what is the best thing to do to try to save this thing?
