Algae Question

[MGR201]

At the time I acquired my clean-up crew several of the Astrea snails had small fuzzy red algae growths on the shells. Now, six months later, a few of those growths have transferred to my rock work. The snails sometimes clean each other's shells and their algae seems to have abated but they seem to avoid cleaning the small patches that have transferred to the rocks.

Pictures attached and I'd appreciate a species identification and suggested remedies.

I've seen that kind of algae before, on my snails and on my rocks. It's not a problem (at least for me). Stays confined and doesn't spread.

I don't really know the name of that turf red algae but I also have it in many places in my reef. It is a good thing and I would leave it where it is.
Don't worry about it.
