Organic Stains
Spot dosing with granular chlorine is the easiest way to remove stains. Care should be taken not to bleach the pool surface, particularly when treating a patterned vinyl liner. It is suggested that the chlorine be suspended near the stain (use a synthetic sock or panty hose).
Metal Stains
This is a very complex subject. Metal stains are normally caused by dissolved iron or copper. Iron stains appear as a brown or rust coloured discoloration. Copper stains appear as blue, gray or black discoloration.
Iron Staining
Occurs quite often in fibreglass pools. Traditional methods of treatment have included addition of various organic acids. These tend to alter the water balance significantly and may affect the chlorine reading on conventional test kits.
