Substrate Q

[biotoxin]

been reading around some other forums and read about someone doing their next tank with arag sand and coral skeletons. Anyone done this before or even know if there's a place that has it premade? Or is this really just crushed coral?

Coral skeletons sounds like crushed coral to me.

I prefer a sandy bottom myself. The CC stuff just looks too rough for my tastes.
