and once again people are going to argue. So before all the fun starts, a little background. I have kept & bred leos (as well as many other species of herps) for over 9 years. I used to use calci sand but switched to play sand for my leos not too long ago. With that said...I HAVE NEVER HAD AN IMPACTION PROBLEM WITH ANY ANIMAL I HAVE EVER KEPT! I still have the 2 leos I started with, they are now fat, retired breeders. Everything I am saying is based on years of experience and a good knowledge about the natural environment of leos. YES, they do live on/near sand in the wild. They hang out mostly in the rocky outcropings, but there is sand everywhere. That is how they are able to dig little holes to sleep in and deposit eggs. You need to be careful of a few things; 1) don't allow leos to eat the sand, I think you already took care of that with the calcium dish. 2) provide a good supply of water, even when the geckos walk through the water & then the sand, the sand just dries up and falls off. (All of my leos also have all toes & original tails). 3) keep an eye on their droppings, if you see more than just a little sand, remove them from the sand. (I have never had this happen.) 4) make certain the moist hide is easily accessable. 5) Don't use piles of sand. My enclosures have about 1/8" of sand on the bottom. 6) Clean out the wastes everyday. This is actually easier to do on sand than with paper towels. 7) I completely replace the sand every month. 8) Don't put any leo younger than a sub adult (I wait until they are about 6-7 months old) on sand substrate. 9) Try to give then climbing rocks of areas where they can get off the sand if they want. The picture below is of one of my leo enclosures, I just took about 5 minutes ago. If you have questions feel free to ask. Let the fun begin!
