Sorry for the wires and everything just set up my control board and getting everything set. Never run white lights so I didn’t realize how ugly the rocks look lol. Tank has been running for a few months can post parameters if needed

Could be sponges or tunicates; why do you want to remove them?

I don’t mind keeping them if they are good! I just assumed they were a nuisance since it’s growing all on the rocks. I don’t mind them though
