Is is safe to get the shells and rocks of the Long Island beaches and boil them and use in a FO tank?

boil 'em, expose them to uv, bake them, put them through freeze-thaw-bioling cycles, autoclave them etc. either of those are fine. me personally, boiling for 15 min is good enough. if you are paranoid, bake at 450 degrees for however long. you will kill everything!
