You might also want to mention that numerous studies discuss the uptake 
of other trace  metals (Ca substitutes like strontium), and I know of 
numerous papers (authors present on the list?) that discuss uptake of 
uranium and radium into coral skeletons, or cadmium, nickel, etc.  
Additionally, other materials are routinely part of coral skeletons, 
besides calcium.  Organisms also bore into and grow in coral 
skeleton...worms, fungi, etc.

One might want to use this sort of "spin" to get help stop the coral 
calcium trade by making it sound as if those who take it are 
potentially ingesting toxic, radioactive worm and fungus filled 
material.  That ought to stop some people who buy the "hype"
