Should I try the calci-sand again with my rosies?

Since my Bonnie passed, I have this huge EMPTY glass enclosure of a showpiece dividing my ginormous living room. I think I wanna put rosy boa into it, and "trick it out" with a cool desert scene/natural habitat. I have used calci-sand in the past, but have lost a baby rosy from impaction by it. It would look super cool and natural lookin', but I'm afraid to use it again on any of my adults. i have since then switched to crushed walnut, which works great, but particle size is bigger, and doesn't look quite as nice as the sand does. Any suggestions?

anybody?????? lil help here???

I'd suggest the fine particle play sand from Home Depot/Lowe's/Local Garden Supply Store, etc. Doesn't form cement when it gets wet and it's pretty safe. I know I ate a good bit of it when I was younger ;)
