It depends. What sort of fish do you have in your pond? Any amphibians? Snails?

Also, why are you adding salt? It's useful as a medication, but the main reason people add salt is that it will cause fish to secrete a thicker slime coat. And the reason they will secrete more slime is that they are freshwater fish, and need to protect themselves from the salt. Many disagree with me, of course, but it seems to me that most of the fish we keep evolved for millions of years in water without much salt, and hence, they're really better off without it.
