Reptisand is actually not even healthy for reptiles. The calcium carbonate in it is more likely to cause blockages than regular sands.

This thread has a partial explanation of the dangers of reptisand: http://www.reptileforums.com/forums/...ad.php?t=51112

It sounds like Wormwood has you headed in the right direction.
