Is your sand really that white? Or a light tan? Where did you purchase it?

Yes, my sand is really that white.
I get it here in Vancouver, B.C. from a large pool supply store - it's a no-name brand white silica quartz-based PFS
(likely from stone quarried here in B.C. or Alberta).
The pool filter sand carried by pool supply stores can vary a great deal depending on the region where the stores are located in N. A.
It can vary a lot in color, grade, size, density, and freedom from dust and grit. In some areas I'm told it can be almost impossible to find white sand. You may need to do a lot of searching & inquiring in order to find some, if that's what you want.
Many pool or spa supply stores do carry off-white shades, or light tan colors that are lighter-colored than beach sand, or even light grey sand.
Hope you find something you like.
