Little help to ID these white things

[mcga]

Hi Reefers ! Happy Friday to all.

I tried to ask Google and Claude before I bother you but they don’t know what this white thing is !

So I am seeking some help :)

I’m more interested in knowing what are these white things …

Thank you so much

I’m pretty sure these are pineapple sponges, I had them as well, you can find details in my post, and how I ended up on R2R

They bloomed a lot in my tank especially in corners and around my skimmer. I cleaned them a few times and they are almost gone now, so it’s just a phase I guess
