ID on frag plugs please

[Hurricane Aquatics]

Crazy phone...sorry for the multiple posts.

Need an ID on these please. Two plugs have white, stringy growths.

Third is supposed to be midnight clove polyps, but looks like something else growing?

White stringy stuff is a sponge. You can scrape it off

Thanks Scott, any idea on dark growths on polyps?

Might be some sort of algae. Hard to see. Best to be removed though.

Poriferan sponge. Can get evasive.
You can trim off or expose to air. Do so out of the tank to reduce chance of any toxins

I've got it in my sump...? Is that bad?
