its alright, pretty much just like tanked, except you dont see any tank fabrication just planning, then the coral inserts, then the installation, and then the final product. They made a tank last night for an indy car driver named Ryan Somebody. His biggest concern was being able to leave the tank for at minimum a week at a time.. they installed a battery backup air bubbler and apparently thats all you need to leave your tank unattended for a week at a time on a regular basis. The thing that gets me with these shows are the people getting the tanks obviously have no idea of the work thats involved with any tank, let alone these giant custom tanks. maybe theres a whole bunch of behind the scenes they just leave out of the shows but unless these people are paying aquarium maintence guys to visit at least a few times a week i'd doubt they keep these tanks for very long.
