Kosher salt is usually not iodized. Most "table salt" is. Sea salt has lots of minerals that are somewhat undesirable in freshwater, and any pollutants from the water you collect would be present in the salt that remains after evaporation. It isn't a great idea, even if it was for use in a marine tank.
