Will this work for a leopard gecko

Answer by Chewy • Nov 11, 2021
Reptilite sand, is made for use with animals such as leopard geckos. As with any sand substrate, we recommend that the animal be nearly full grown when kept on Reptilite and that feeding not take place on the substrate.

Is this a pure white sand?

Answer by Chewy • Jun 14, 2021
This all natural calcium substrate is made of aragonite sand.

Would this be okay to use in my gerbil’s sand bath?

We have multiple bearded dragons and this substrate is so much cleaner. I just sift it regularly and no smell. Very easy to keep clean and I change it out every few months. Definitely recommend.

Super fine and sticky

I dont know if I just don't like this or if I'm using it wrong. I felt like it stuck to everything and was so fine that it was practically unavoidable. I ended up mixing it with other things. I don't think I would ever use it as a sole substrate.
