Do you have an urchin?

yes to an urchin a small one but it has never eaten pieces like that .

Usually white in coraline algae is an indication of growth or death. Any abrupt changes in tank chemistry that might of caused it? Other than than that the only thing I could attribute it too would have to be your urchin, they are known for it after all.
