How much lr
and sand do you have now? What other types of filtration, if any do you use on your current tank?
If you move everything, including as much of your water as possible and what ever filters you are using now, to the 90 you shouldn't have a cycle. if you add more lr
, make sure it is cured. You can add dry sand withouit any problem. Basically you are just adding alot more water volume. Everything should be fine in buckets or something as long as the water doesn't get cold while you make the move.
Flame scallop won't live very long, as mentioned. What kind of anemone and what type of lighting do you plan for the 90?
