I use sand but only on my two adults who have been on it for about 13 years. I have never had any problems with it but I also am a clean freak and I change it monthly. I have a moist humid hide for them to go in when shedding. I also check there toes to make sure they don't have any skin left on them after shedding.
I DO NOT recommend using sand with babies less then a year old because of the risk of impaction. I also feed my geckos in a plastic tub so the risk of ingesting sand while eating is lessened.
I keep all my babies on either reptile carpet or newspaper. I soak the reptile carpet in warm soapy water and the let it dry for a day before putting it back in the tank.
