Avoid Caribsea Tahitian Moon, it's black, but sharp.
You could get a bag of one of these sands and use a measuring cup to sprinkle it on the bottom of your tank and get some good cover. It will cloud the water up for a few hours but the filter will take care of that in a few hours.
Oh and it's a bit pricey at PetSmart (like 25 bucks), I would buy it online if you can. I found a LFS that sold it for $16 for 20lbs, that should be enough.
