What kind of sand do stingrays require?

WHY is poolfilter sand "best"????
 
I used sand from a river near my house.

Sent from my Comet using MonsterAquariaNetwork App
 
Live sand is just aragonite...not much "live" to it other than it being soaked in water and supposed "beneficial bacteria".

The aragonite would buffer the water to a higher hardness and in some cases pH as well.
