I am old school. I have never found a "instant" saltwater biological additive that worked any better than seeding a few pieces of live rock and waiting a bit. The live sand I saw them adding looked to be in dry bags and would seem to have little biology going on there. Again, I like their traditional tanks, but their theme tanks are as worthless as the choppers they build on American Chopper. A giant bubble gum machine fish tank in the Vegas outdoors is asking for trouble. And some of them look impossible to clean.
