Okay, I just recently placed new Ocean Direct sand into the tank (new set up) and placed 50 lbs of base rock and 4 pieces of live figi rock, all last week. Today, I noticed this growing onto the base rock near the bottom. I just started cycling the tank but I can't imagine something is growing in there already. I have no lights either yet.
This object sways back and forth with the current and is soft to the touch. What is this? Is it bad and should I remove it?
