Building new rock structure

[tmb1891]

So im in the process of setting up my lagoon 50g and I wanted to use some old deer skulls I have in my basement to incorporate into the live rock structure. They were cleaned out and bleached years ago. I wanted to cover them in coral but I wasn't sure if it's ok to use old bones in the tank. Any thoughts?

Not sure how it would look but, the bones are just made of calcium so I don't see a problem there. As long as there are no traces of dried flesh, hair, or skin.
Be sure to post pictures of the build.

Just remember bones are a compound of calcium, phosphate, and MANY other trace elements.
