Conrats on the pickup
Amd on another note, sand isnt the best, but it's not too bad once their adults and don want to eat EVERYTHING.. Once my guy was full grown we put him on sand, and there were no problems with it. In Australia, they live on sand. And I went through my sand to make sure there was never anyhting in it- there theres no one to do that. Course, they also eat wild bugs there too, which I NEVER fed him anything from back yards or places I didnt trust, but still. Now for babies, I never would. But they should be fine.
