Our well water smelled awful. Rotten eggs, sulfur type of smell, and had a rust color at times. After reading different ways to deal with the problem, I bought this treatment. I followed the directions (maybe used a little more chemical than needed). I let the chemicals to there job in the well for 8 hours. I then began to flush the well. It takes a long time (several hours at my house) to get all the chlorine smell out of the water. Don't attempt to rush the process. Good thing is that it's not been 7 months since i treated the well and we have no water odors and the color of the water is noticeably better. Don't forget to flush your hot water heater.
