getting rid of GSP

[russell_wiley]

Does anyone have a good way to rid a rock of GSP? It is encroaching toward my SPS. I like it, but, I need it off that rock. Anyy suggestions would be helpful.

Thanks,

Russ

The only effective way was either to kalk it (may get on something else) or take the rock out and peel that greyish base that it has off the rock (the only sure way).
