I could write another novella here regarding the stuff on the market for reptiles. I'll just add one for the moment. Calci-sand. Every one of the companies that produces reptile products has their own version. It is not only a waste of money, it can be dangerous. Calcium carbonate, which is what is added to most of the products, and is the base ingredients in most calcium supplements, is also a needed ingredient to turn sand into concrete, because when mixed they clump in water and have a difficult time dissolving. This is not good in most reptiles stomachs. And since it does have calcium in it, some lizards will lick and eat it trying to get the calcium.
There is a large debate among many people as to whether to keep certain species (bearded dragons, leopard geckos, etc...) on sand or not, but that is for another debate. If you are going to use sand, buy plain play sand, sift it once if you like to make sure there are no pebbles. It is 10x less expensive, if your animal does ingest any it will be much easier to pass, and they will be less likely to lick the sand by itself, even if they are hypocalcemic, (once again, a separate subject, and the reason that many people who buy this stuff end up with animals eating it.)
