Do you mean Astraea snails or Asterina stars? I'm going to assume Asterina starfish... You can just keep on course and manually remove them, or explore a harlequin shrimp, which eat starfish. It won't be an overnight cure, and may take some time. Also, these primarily eat starfish, so if it does eradicate all the Asterina's, you will need to re-home it, or purchase starfish to feed it.
