thoes look really good, when i have my big FOWLR i was thinking about doing the whole fake coral thing. I wonder if you didn't put coralline in the tank to begin with it would keep the fake corals cleaner. Like if you started up a tank with just baserock and fake corals and livesand in the bag, you could avoid coralline in the tank, but the rock and everything could still hold the bacteria, hmmmm wonder if that would even work lol
