you bet... Just make sure you get the "Yardright" or "Southdown" brand, this Caribbean playsands are 100% Natural calcium carbonate a.k.a Aragonite..
Now, don't get confused cause they also have some other sands which are silica-based or Quartz-based. they're ok but not as good as the white calcium carbonate Playsands..
Silica- and quartz-based sands are fairly inert and also alright to use, but will not give the same buffering benefits of aragonite. they would also tend to be darker and bigger grain size..
