Working with a 72 Ga. Oceanic tank. It will be here tomorrow or Thursday!

I've already picked out a good skimmer and two powerheads with the help of some people on this forum. I a couple weeks, I'll be adding 100 lbs of live rock, and then the substrate a bit later. I am really wanting to use pure white sand for the substrate. I love that white sand from around the FL panhandle beaches! However, I was kind of wanting to go with live sand, but even the live stuff from the Gulf everybody is selling is not white. Looking to go really find grain substrate. Any suggestions as to what might be a good compromise product? Thanks for any info or help.
