Thanks for the info! I might have to try the sand route sometime in the future. I think it looks much better than aquarium rock. I always thought it would be too tough to clean. :duh:nursie said:You kinda swirl the python over the sand...it gets most of it up. You can dig it down in a little bit, but pull up quick before it pulls sand down. I use sand because I have plants, and the poo, etc is mulched by the snails and goes into the substrate some too.
