We have move our tank four times. The last time we upgraded froma 55 to a 150, but a previosly owned tank. What we did is transfer 50% of the water from the original (150) tank and bought premade water from the LFS
. What a pain!!! When we move for the last time into our house we will have all extra water needed pre made at the house. Take all the tank water you can get out of the old tank or 50% of the volume of the bigger tank as others suggested. You'll still get a small cycle (or a little algae at first) but if you do it right you won't even notice it.
