Hello, I want to change some of the substrate in my beardies enclosures I have tiles and rock, I want to add sand to one half, is this safe ? I have read dont do it, and its fine. My beardies arent young ones, they are 3 and a half years old. I have read to use the play sand found at Bunnings. So is it an issue or not ? Do you have some sand in yours, if so, how long have you used it for ? Do they eat it, will it be impact issue ? --- Automatic Post Merged, Oct 8, 2019, Original Post Date: Oct 8, 2019 --- Or better yet excavator clay anyone used it ?
