I thought the same thing when I first saw the show. When they make the really big aquariums that are parts of the walls or simply large, the aquariums are put together with an R/O system
. So the tank water is constantly filtered to remove debrises and keep ammonia levels low. As long as the owner replaces the filters and membranes on time the fish should be fine.
Note: The link only goes to examples of R/O systems you can buy. If you want to know more, you can wiki reverse osmosis.
