There's no such thing as an instant cycle. Just take your time and let the tank turnover for a day. Amquel is a great product to have on hand for transfers. The possibility of having an ammonia spike is real when moving that much live stock.Ah okay this is a good idea! So basically a week for them in temp holding to allow for time to set up the tank in its entirety before moving them? Did you test the tank all the time like when youre doing a first cycle with all new stuff or was it essentially instantly cycled with the live rock like @EeyoreIsMySpiritAnimal was talking about earlier? I know Im going to need to also get new rock since the tank volume is essentially doubling and I would like to make a bigger scape for the fish. Just wanna make sure Ive thought of all the potential problems before deciding on the exact tank and doing the move!
