No, you need to remove the jelly like crud if it is going on this long.
If it will siphon off, do that.
If it is very serious and covering a large part of the coral, put it in a bucket of tank water, blast the goo off with a powerhead or turkey baser, and put the coral back in your tank, with increased flow. And toss the goo water. But it sounds like it is only on a small part of the coral, so you should be able to siphon it off.
9 times out of ten when I have a leather not looking well, they respond well to more flow, even if things had previously been to it's liking there.
