I did 2 moves with my 155 bow. Used pumps with screens on the intake, with heaters plugged into an inverter. Keep as much sand as you can and if you have lots of live rock you will be fine, either one, you should not get a cycle. If you have a shallow SB or no SB then your going to need quite a bit of live rock so make sure you don't get and cycle, I had about 200lbs LR and no sand with no issues.
