Green looking slime
A couple of pieces of our liverock has a green looking slime on the underneath of it. These two pieces are not touching the sand bottom, they are two flat pieces that are the supports for a cave of sorts. So the bottom of these pieces are visible.
My tank is in it's 3rd week of cycle.
The live rock came from a person who had broken down his tank and it was in a pool outside where I believe sunlight maybe hit it about 30 minutes in the day.
Should I pull the liverock and scrub it?
Should I wait for cycle and get some type of fish or crabs to clean it?
