How can you get your salt water pool to smell better cleaner like a chlorine pool?

It sounds like you need to look at the water balance. there would be no swampy smell coming from the pool if the sanitizer was doing its job. I suggest you take a sample of water to your pool shop for testing they will be able to advise you as to exactly what tis wrong with the water. In the mean time it may be a good idea not to swim in it until it is fixed.
