White Fuzz? (1 Viewer)

[Makatiel1978]

I have this white fuzz growing at the base of my Candy Cane Coral and around some zoa polyps on another frag.
Recently started to get a few Pineapple Sponges but I have no idea what this fuzz is.
It’s soft and does not seem to be bothering the corals at least not yet.
Just wanted to see if anyone knew what this is and if so is it good or bad?
Thanks

Sponge of some sort. I have it too. Kind of annoying but doesn't seem to bother anything.
