Great question, Sherrie!
You would add this any time you add new water to a tank, new fish, when fish are stressed, or once daily during illness. As for during transport, just add it whenever you add water to the transport container. If the transport is going to take a day or two, then be prepared to change a little bit of water about every 6-12 hours, depending on how many fish are in a container, and add some of the conditioner each time you change some water. Add for the amount you are changing or as close to that as you can get. An overdose of twice the normal amount is safe.
