I'm sorry, but that is not an adequate treatment for ich. Due to the ich life cycle, it will return if it's not treated for 14 days.Repeat the water changes every day after this but only add 4 1/2 teaspoons of salt to the new water to replace the salt taken out. And dose with the rid ich+. When the fish gets better and shows no spots for 3 days, you can return to your normal water change schedule and discontinue the salt. I hope they get better.
Here's a wonderful article about treating ich with salt + heat, which works far better than medications:
