I get that you're using naturally poo-eating bugs to eat the snake poo. But... What about the bug poo? It stands to reason that some portion of what goes into the bug comes back out. I'm sure the bugs make finer grained droppings that are much less visible on something like coconut fiber, but it doesn't seem like it would actually reduce the necessary cleaning interval all that much. (And if you can't easily *see* the substrate getting dirty, you might end up letting it get much dirtier before cleaning than you otherwise would have...)
