this is a huge debate. it pretty much depends on the clam itself. all clams will do better under halides, but some have been able to at least SURVIVE (although after losing a lot of color) for periodes of time under PC. however, i dont think 5.2 wpg of PC is sufficient for any clam. esspecialy not on the sand bed.
they look nice though.
