Swimming pool stains are mainly caused from too much iron and copper in the water. Iron stains will usually be brown and rusty looking. Copper stains are usually bluish to grayish in color.
When your pool’s pH is too low, the metal in the water stays within the solution. When the pH is too high, metals in the water cling to the walls of your pool. There are several steps you need to take to rid those metal stains.
- Identify the type of stain
- Prime the water chemistry for stain removal.
- Flush the metal from your system
Stains can come back. Every time you add water to your swimming pool you are adding more metals. You should use a stain and scale preventative product each time you add water. You should also backwash your filter regularly. Anthony Sylvan Fiberglass pool builder assures you that maintaining pool chemistry is not as hard as it sounds.
