I am considering getting a 75 gallon (18L x 48W x 20H) for my Patricias. Part of my thought process is to have a false bottom raised about 4 inches off the tank's bottom. This would allow me to add a small and shallow pond area with a small wandering stream that would be "powered" using ReptoFilter aquarium filter, normally used for turtles. Theoretically, the filter will not only provide a means of moving the water but keep the water "clean". I would camouflage/hide it within terrain. I am curious as to why the half-bottles were covered in sandwich bags. I kind of like the idea of using hamster tubes. I would add 3/8 inch clear tubing to change / drain water as necessary.

Thoughts??
