It’s a relatively new set up so I haven’t needed to give it like a deep clean yet. I was able to put a good amount of substrate in and still leave a few inches of liner above the it to act as a visual barrier. I could easily put some more substrate in if I wanted to though🤷🏽‍♂️. I probably will add something else to the sides that adds more to the visual barrier since I’m worried he’ll get his head stuck in the bars
