My IM Fusion 20G is on day 10 now and is showing very healthy signs of green and red/pink Coraline growth. After the introduction of some small frags (Xenia, Duncan, Zoa, Torch, Star Polyp) on day 7 they're all settling in nicely. I would never have thought it possible to cycle a tank this quickly but by using "Instant-Ocean" Bio Spira, sea water as opposed to a bought salt mix and dead tonga reef rock (soaked in sea water for 3 days - changing everyday) its levels where consistent on each test. Naturally I am expecting the tank to crash somewhere along the way but for now I think things are looking pretty good. Have gone with smaller frags to allow for growth and the introduction of an anemone.
