I have four and they do eat the coraline, but I still have a total purple covering. (180 gal) I wouldn't think that they would dent it too badly.

There is an old saying...go with what you know. Those crabs will eat coralline algae, you are having difficulty getting the algae...why ask for trouble. There are other scavengers that will not hurt your coralline. Once you have strong encrusting, get some more.
