hi everyone, I’m planning to upgrade my 20g nano to a 73g reefer 350. I’m planning to remove all my existing live rocks (20lbs) into the new tank to aquascape with some additional new rock, and let it cycle for about a week before I move everything from my existing Nano tank. Will my 20 gallon run okay without the live rocks? I only have about 1inch sandbed in my Nano. What is the best way to do a tank upgrade?
