Sand (including calcium sand) or loose substrate of any kind is no good for lizards that 'taste' their surroundings, like leopard geckos and bearded dragons. Their tongues are sticky, licks the sand and swallows them. If it is hunting loose crickets in the enclosure, it will inevitable swallow sand along with the insect, risking impaction in its gut. Impaction is fatal if a vet does not intervene asap. Wild bearded dragons do not live in sandy environments as previously believed. They actually spend a lot of time on trees and branches and lives in terrain that has a lot of rock and pact dirt, not soft loose sand.

The better substrate alternative if you want to keep the natural look is to use tile, rocks, and large pebbles (Bigger than its head).
