You should be fine as long as it doesn't have silica in it.

I use 3m Color quartz, it's around $20 for a 50lb bag.

There is lots of silica in poolfilter sand. In all sand.

And yes, your rays will be fine.

"The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with a chemical formula of Si O2 and has been known for its hardness since antiquity. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms. Silica is the most abundant mineral in the Earth's crust."
