#brownjelly

Does this look like the frogspawn is covered in brown jelly? Coral was receding yesterday and today looks like the attached pictures. The corals have had brown spots appear on them for months. They looked more like they are browning due to lights or trace element issues and not jelly which...

Does anyone have any clue on how to cure this without discarding the Duncan I’ve already lost one from the jelly, and I don’t want to lose anything else, also would it actually infect other coral or just Duncan’s?
