Can anyone tell me what this is?!?!?! Are they some sort of pineapple sponges? Their all over my sump, havent seen them in my main display yet. Should I be worried

Yup pineapple sponges. Pretty common in new tanks. They are harmless and will go away over time
Thank you! I did a little more research on them and definitely see they ain't something I should really be to worried but might have to check my RO/DI just to be sure 😅
