of the extremely conflicting views you will get on husbandry! LOL
Steve, if you read the rest of this thread and the other thread st00ps started, you will see all the reasons why the rest of us dispise calcium sand with a passion. All the things you read on the bag are a blantant lie. It does not digest easier, it changes the PH in the stomach acid (think TUMS) and actually SLOWS digestion! Put some in a glass of water for a few days and see how well it disolves (NOT!) And if you are supplimenting with calcium in their diet like you should why do they need to eat sand for calcium? It's just a marketing ploy.

"Calci-Sand
T-Rex touts their Calci-Sand as a calcium supplement. Unfortunately, this is harmful for most reptiles, such as green iguanas, as if they do ingest it, it will cause impactions, just like all other particulate substrates. Desert animals who live on sand don't ingest enough of it to make it worth the expense, not when plain, cleaned playground sand can be purchased for about $5 per 50 pound bag. Bottom line: The way to prevent metabolic bone disease is to provide a proper calcium supplement for those species who need it; feed healthy prey to carnivores and insectivores; and provide UVB-producing fluorescents or direct unfiltered sunlight to those species dependent on UVB for the formation of pre-vitamin D for adequate calcium, not dump a bag of an overpriced, potentially harmful, substrate into their enclosure."
And read thes rest of these threads. Calcium sand is bad, bad stuff and the companies that sell it are guilty of false advertising. It sounds like you are a victim of this false advertising, but I hope you will change your mind.
