jelly disease on SPS! Or something else?

[Jerokane]

I see it appearing on other healthy SPS and frags too!

Just looks like polyp expansion. I see it all the time on sps, especially montis. I see it a lot at night and after I dip them. No worries. It'll be back to normal soon.

Are you absolutel sure? As I have never seen it like that.

I am talking about the whitish yellow jelly / slime bubbles on the underside and edges!

I see it appearing now also on other SPS, like lilapora.
