I would not advise the use of ocean rock or water. In order to find rock that would be "safe" to use, free of pollution and such, you'd have to go pretty far out into open water (at least 10 - 20 miles away from shore). Also, if buying fish from a LFS, the exposure to illnesses, parasites in particular, and exposure to possible pollution issues could be deadly. Also, it should be known that there are laws about collecting live rock from the ocean, and without the proper permits, there are huge consequences if you get caught.
