Reptichips is nice stuff. A lot of retic guys rave about it or paper. It's nice in that is fairly cheap and you can just throw it out every month or two. I just got tired of having to prep it every time i wanted to use it lol. I mean you could just get 2-3 66 qt Sterilites and just mix up 3 blocks and have it ready. But that is really my only gripe about it. And one other thing, being big pieces, it does allow liquid to seep down some and big snakes can hide pisses in it. But for the smaller snakes, it works fine.
The only substrate i found so far that can contain a Caesar Tsunami is aspen. Anything else just cant hold up lol. I ordered cypress so we will see how Caesar handles that.
