Some people do use aquarium salt to help keep up water quality (kosher salt is also an option). You can buy it rather cheaply (Dr. Wellfish in the pet section at Walmart comes to mind). Follow the directions on the box. Because it doesn't evaporate when water does, you'd only want to use it when doing a full water change.
