Either/Or will be fine. If you put in with an empty tank and start using it, the fragrance and active ingredients will help with odor as the tank fills. If you use when a tank is full it will help clean and deodorize the tank up to the water line. It's really personal preference on when you think you need it due to odor issues emanating from the holding tank.
