3 S alt – The actual salt you use can be the most common cause of staining as it contains metals such as iron and manganese which over time fall out of solution. 3 O rganic Stains – These are caused by algae growth, leaves or dirt washed into the pool and left longer than a week. 3 L iquid Chlorine – Has a high iron content and after continuous use for many years this can build up and lead to staining.
