Does Estes Sand Has silica??!!!

Why don't you want to have silica? If you take silica out of quartz sand (silicium dioxide), there's not much left 
. You don't want to have any calcium carbonate in your freshwater sand, if you don't intend to have a rift valley tank, because that makes your water hard. Just treat a sample of your sand with acid and look what happens. If you get bubbles, use something else.

I've read alot of people using estes sand but not so many that have rays. I just wanna know if I can use this sand with rays
Okay, I read the freshwater stingray entry, and the problem seems to be silica's hardness and sharp edges. I'm not sure whether there are silica sands available with rounded edges and fine enough granules, but that should be possible. My (silica) gravel has rounded edges, but it's not fine enough for rays. I'm not sure whether limestone sand is the answer, as mentioned above.
Perhaps, you could just look at the granules under a microscope or a magnifying-glass? If the edges of the sand are eroded, it should be fine, even if it contains silica.
