Problem to zoas/palys?

[62SVT]

I was checking out my tank (like I do 100 times a day) and noticed this white stuff starting to creep up around some of my zoas/palys. I belive it is a type of sponge or something similiar just from reading, but want to check and make sure it wont harm the palys/zoas. Any info or proper ID would be helpful, Thanks!

Only pic I could get to load. After looking at it again, it may be some type of algae?
