Strange growth

[hurrifan]

Advice needed - I have a strange looking organism growing on my rock, corals and glass. It started on the underside of my hammer coral and then spread. It white (yellowish) and resembles mold, like you would see on decaying food. I think it may be some type of algae, but have no clue and if so, how to treat it. Everything in my tank is doing well, except my leather coral (which I do not believe is associated). All levels are fine. Any advice or guidance would be appreciated.

Could it be the white coralline algae?

It would be hard to say without a picture, but it could be a sponge.
