HELP! Is this brown jelly disease on my Duncan?

Is this brown jelly disease on my one Duncan coral? It wasn’t brown this morning, I came home and suddenly there was this brown stuff on it!

Looks like algae me.

Thank you for replying! Would this type of algae be dangerous to the coral? It has been retracting a lot more lately

Yes, it is, the algae will spread and in the end, kill the polyp.

Is it stuck on the coral or can it be gently blown off?

Some pest type algae’s and bacteria’s just can be removed.

I gently rubbed it off, my concern is it spreading to other corals or coming back. I am currently dealing with large cell amphidinium dinos, but I heard it’s not supposed to be toxic to corals

Any Dino’s I’ve worked definitely made corals upset.
In the end will kill by covering.

Do yours lift off the sand a rock at night, then reappear in the morning when lights come on.?

Yes, which is why I held off on using UV. I was told to slowly increase silicate to create a diatom bloom and create competition.

Winning Dino’s is a numbers game.
I’d be running UV while dark and change socks when lights come on.
Keep nutrients up and a daily dash of bacteria and phyto will feed the good guys which outcompete the Dino’s in the end.
About a month this way.

Will certainly do these, thank you!
