From my understanding calci-sand is okay for adults (not good, but the chances of it causing problems is very small) however play-sand isn't really the way to go.
Reason why:
- Calci-sand is made of calcium carbonate which after a while is digested and absorbed. It will only lead to impaction if ingested in large quantities ( which if you have a well fed and well supplemented gecko should not happen).
- Play-Sand on the other hand is made of non-soluble non-digestible minerals. This means that the sand particles will not be digested and absorbed period. And while some of the sand particles may leave the system undigested, not harming the animal, it still leads to a high risk of impaction.
Remember, leopard geckos in the wild generally live in rocky, grassy areas, not ones where there is much sand. If you want to make your pet more comfortable, you should take that into account.
sorry, i couldn't disagree with you more on this. calci-sand can actually encourage a gecko to ingest it much the way they would from a calcium dish. i would never use calci-sand as substrate for ANY of my reptiles. I lost a beardie a few years ago from impaction due to calci-sand, and nobody will ever change my mind on this. as far as play sand, i only use washed play sand for my beardies, never for geckos. i have a friend though that used a non toxic glue, mixed with washed play sand, and formed caves and inclines that hardened solid. keeps the substrate look to it, but without the loose particles. i will only keep my leos on paper towels, but again it's a matter of opinion. and that's mine, lol.
I'm thinking of going the bioactive substrate route in a few of my tanks that open from the top as opposed to the front. Have to wait till it warms up to go collecting out in the woods, though.
