White mold looks like cotton ?

What's up guys it's been a while since I've posted anything on here. I've had my 60 gallon saltwater tank with about 40 pounds of live rock up and running for about 10 months but recently I've noticed this kind of white cotton looking mold can anyone identify this and tell me what it is ?

It is sponge growing on your live rock. It is rather normal and IMO a sign of good parameters.
