Substrate

The next thing is substrate (flooring). There are many options here. I used astro turf for a while, but it is difficult to clean and you have to remove everything from the tank to do it. Also, tiny pieces of this "grass" can be accidentally ingested, causing major problems. I also avoid wood chips or bark. Leopard geckos are very soft skinned and these may be too abrasive. You can also just use newspaper but it will need to be changed frequently. I have found that sand works great. About an inch deep is plenty. Droppings and debris can be removed using a small sifter...very low maintenance. You will just need to replace all of the sand about once a year or so. Do not use play sand! The sand in a lizards tank has to be digestible. You can pick up reptile sand at your local pet shop. It's very inexpensive, and they usually offer a variety of colors. Reptile sand contains calcium which is great for geckos.
