How much of the bath salts you use is up to your personal tastes, and your personal tastes will also dictate how much fragrance you use. Some people like a very light scent and use just a little amount of fragrance oil. Others want the entire bathroom to be scented. The size of the bath tub will affect the amount of salts used. I use a much smaller amount of salt in a standard sized tub versus a large jetted tub. I think that the practice of testing until you find the right amount will apply for finding how much salt you want to use.

I hope this answers your question.
