What is this on my hammer?

What is this? Hammer is doing well. Opens up and seems to be happy when the lights are on but what is this and should I be concerned?

The white specks look like spirorbid worms. The purple is probably coralline algae. Is there something else you’re talking about? Hard to see the pic.

The purple stuff is coralline algae, the white curly things look like spirorbid worms. Generally harmless.

I was referring to the the purple stuff. If it's coralline alage I guess I can relax lol. Thanks guys.

Does it scrape off if you touch it? If not and it’s hard, it’s probably coralline. Common on these types of branching corals. Harmless.
