While you are doing the water change and tidying the tank up to get it ready for the first few new or additional pieces of livestock, it's a good time to make any aquascaping changes you desire.
Once done and the system is restarted, let the tank run for a day or two to allow it to settle out. During this run time check and make adjustments to parameters of the aquarium water that may be needed, such as the temperature and salinity.
