You can try a bleach solution on the stairs and if it lifts you know it was organics that caused the staining. Otherwise it could be metals - perhaps iron staining. If you rub a lemon/lemon juice on the stain and it would lift then it’s iron. Start with the bleach solution first.View attachment 594875Pool is draining!
