Works extremely well for urine breakdown and odor

This is so great. I use it as the only substrate for my non-burrowing snakes. While it may seem pricey, keep in mind that it will last for several months and keeps the enclosures smelling clean. The bioactive properties seem to break down urates very quickly. I recommend utilizing a humidifier with controlled humidistat if you are using this as the sole substrate with snakes requiring higher humidity levels (pythons, boas, etc). You will need at least 3-4 8.8lb bags to cover a 4ft x 2 ft enclosure floor with sufficient layer.

You pay for the quality. Japanese volcanic soil substrate that makes the best drainage layer can even be used instead of Fluval to plant aquariums. My photo may be a tad dark, but if you can see, I indeed have that drainage layer.

I got this for my leopard geckos and they love it I never seen Nemmy run so fast in it and you don't need to worry about them eating it compared to others it's not loose like soil it's like beads and make a cool sound when wet looks very cool in tanks as well worms can't dig under to make them easier to eat
