What are those? They are around my skimmer and water column.
Any way to get rid of them ?

They look like hairy pineapple sponges lol.
@ISpeakForTheSeas would have a better determination.

Haha, they are pineapple sponges (genus Sycon), so they're harmless filter-feeders and will likely disappear on their own in time - that is some rather interesting growth going on there though.

I don't know if the strange growth is a species-specific thing (there are currently 84 recognized species in the genus, so I'm not familiar with all of them), a tank-specific thing, or just the starting phase of growing more sponges from the same base, but it's quite interesting.
