I know a natural substrate for leopard geckos can definitely have controversy, especially the one i discuss which i am considering getting which is loose eco earth coconut fiber, it certainly is better looking than my dull paper towel substrate currently, it is only impacted in rare cases, obviously as well every one arguing for states the youtube videos of the impaction tests with it and how its been used fine (keep in mind in my case im using loose coconut fiber, not the brick which is boiled and dried out), so is this ok is my question, im looking for it will work, or it will not work, but to explain why either answer thank you.
