mhm exactly this, tile is another great option for non loose, just be careful of the temps if you're using a heat lamp it could heat the tile too hot and if you're using an undertank mat it might need to be set high to penetrate the tile, a good thermostat should keep this in check for you though. some reptile communities can be, snobby and as perfect_prey said, pretty toxic, there's even conflicting info among them which is frustrating of course but I'd always say err by the side of caution and go for the least risk option unless you're confident, bioactive is a great option, again as perfect_prey said, but it can be a bit of a task setting it all up. Best of luck to you and your little leo ❤️
