On the shelf at Wal-Mart I found a product called "salt cell protector" under the brand name "My Salt Pool." The label does not list the ingredients. Mysaltpool.com does not list the ingredients either. Does anyone know what is inside this bottle? It's a 1 quart bottle and claims to treat 10,000 gallons at start up or 1/2 a quart once a month for maintenance. The label and the website claim that it prevents build up of scale on electrolytic cell.
