Okay, the ATBA still hasn't been built, but my goal of having a low maintenance environment has certainly been met. This is 9 1/2 months later without any maintenance except for feeding, the occasional cleaning of the glass above the waterline and adding 5 gallons of water every couple weeks and replacing the basking bulbs (both the UVA halogen (once) and the ReptiGlo 5.0 UVB (twice)). Jordtim has rearranged the sand and decorations a bit, but I haven't touched the filter yet.
