Unless you have animals that are super-sensitive to chlorine, don't concern yourself with the prime. Certainly add it if you want, but don't worry too much about it if you're just doing small changes, and don't worry about when you add it.
Sorry, but I don't think this is good advice to post to a new member asking questions. Prime is inexpensive to begin with. And it is so concentrated that a tiny bit goes a long way. I add Prime even with a 20% water change in a 20 gallon tank. It probably costs me $0.05 to do this. Why even risk harming your fish to save a nickel?
BTW, all fish are sensitive to chlorine.
