I think when you mix salt in a large volume of water, it is much easier to notice the stuff that takes a while to dissolve. If you mixed the salt just in a bucket, you probably wouldn't notice the same amount of cloudiness, and when you do a water change it gets diluted so quickly that you never notice it in the display. It took my tank a week to clear up totally when I first added salt to the whole system.
