Identify this sponge substance?

Can anyone identify this?

I think this is what is causing an issue with some of my corals, specifically the softies.

I wouldn’t remove it unless it was bothering the coral. I like sponges.

There is a sponge that smothers coral, is this growing over live skeleton or just the dead rocks?

From my inexperienced eye, the sponge now covers "land" that once housed corals.

I can clearly see a branch of rock that once had mushrooms now have this white substance. The same can be said on my zoa garden.

I now noticed it on base rock of my goniastria. It does not seem to have overtaken this coral.
