Black pearl like algea

[grandprix30]

It started with one or two little black pearls growing one the rocks. Now I am infested with them. They seem to be filled with water. When I sqeeze them they burst and just a skin is left. Does anyone know what they are and how to get rid of them. Your help would really be appriciated.

To squeeze them w/definitely infest your entire tank. Been there done that . We had it bad. Large ones that we finally took out rock and pulled them off. Don't pop them in tank. It just makes them spread. WE did get emerald crabs to help keep on them and it works fairly well, but we do reach in and carefully pull them out once in a while.
