Save your hard earned cash and buy a good calcium carbonate sand and seed it with some live sand from some established tanks. Your sandbed will be 'alive' before you know it.
I think that is just play yard sand found at toys'r'us, home depot, etc. You can also buy the bags of non live sand for like $8 a 20lb bag at most places like petland discount. It isn't as cheap as the other stuff but I know I wasn't sure about purity, and if I was buying the right stuff then so I just got the aquarium designated stuff from caribsea I believe.
