Please help. Salt for curing Ich? - buy curing salt san diego

Recently, I died my beta fish.
There were other fish with him and I if I had.
So I take the fish out of his car and the other with warm water.
I can not buy anymore to the pet store and medicine, because the nearest is about an hour. I read somewhere that you can use salt preserves. Unfortunately I did not. Can I have a different kind of salt?
