I've had my LR just sitting in my old 90 gal tank with a Green Chromis and 2 black mollies and about 12 nassarius snails waiting for the arrival of my new tank. It's been there for 6 months. I set up the new tank 10 days ago, moved all the LR and some of the LS. Never got an ammo spike. Moved the Chromis, mollies and snails about 5 days ago and all are well. Is it possible to not have a cycle?
