"Tanked" on Animal Planet

[sphelps]

Anyone got any info on what these guys use for filtration? I'm assuming just a wet-dry system and nothing special. Also are they really just using straight tap water and setting up these fully stocked tanks as quick as they appear to be? I'm thinking they have a few tricks up their sleeves that they don't want to become common knowledge, like pre-cultured filters and some kind of inline water filter and salt mixing device. Makes you think though, some of the most expensive tanks in the world (well at least the ones on TV claimed to be) don't use live rock or protein skimmers...

And do these guys ever use real coral?? Or is that something they pretend doesn't exist. My wife talked to someone in Vegas regarding their fish tank in the casino and they were convinced live coral in aquariums didn't exist.....
