Hey, instead of sand, I use specific-reptile sand at the pet store, which looks, feels and smells like sand, but is actually ground up calcium. So, it is completely harmless (maybe even benefitial) for consumption. Will not cause impaction and doesn't cloud up my water. Plus, I would imagine what dissolves in the water makes the water calcium rich, which is a plus too!
