Greetings, well for me it's hard to clearly decipher anything from the pic because it's dark. But, if it's brown jelly the easiest method is to frag the infected heads and give the coral a dip in iodine solution. Brown Jelly will spread to other corals, it goes down the skeleton so you'll have to cut quite a good bit of the skeleton.. For brown jelly there isn't a true cure..
