Advice for tank transfer?

[Madreefer]

Over the years i've done alot of tank transfers and have always used the same water with no problems. Most of them were to a larger system so I just thought of it as a bit of a water change since I was adding new water anyways. I know it does'nt make any sense but it saves on salt. I just did a bigger water change after a week of the tank setup. Have never lost anything in the process.
