Setup my reef almost 3 years ago...battled dino's for a year and a half until the new year when I decided to try out that Vibrant aquarium cleaner stuff. Tank has been dino free for almost 4 months now, and my corals are beginning to bounce back. I tried almost every method to get rid of the dinos, so my tank did inflict some casualties in the ways of coral, but anyways, that's in the past.
