I was rinsing my Caribsea sand and noticed a large black flake in it.
Upon inspection I discovered that it was a coin sized piece of rusted metal, and after running a magnet through the rest of the sand I found many more particles.
To test for holes that could have allowed this metal to contaminate from an outside source I filled the bag the sand came in with water and found no holes.
I wanted to make others aware of this in case any of you have unknown metal in your sand bed right now.
