ID Help Plz

[RobZilla04]

Just need help with ID (white growth off coral base) and should they be left alone or removed??? TIA

I think it's some sort of sponge. I have a ton of it growing on marine pure balls in the sump. If it looks like it's irritating the corals remove it

+1 on sponge.

Not currently bothering any corals so I'll leave em be.
