Azure Stain & Scale Remover is best used for metallic stain removal and prevention of hard waterscaling. It sequesters the material causing stains and scale and holds them in solution. If stainspersist, they may be old, requiring complete cleaning of the walls, or stains of an organic nature. Dissolved metals and minerals (such as Iron, Calcium, Manganese and Magnesium) in pool waterand corrosion of metal pool fittings will often cause staining and/or scaling. Do not let pH of poolwater fall below 7.0 or serious corrosion problems may result. For scale prevention it is alsoessential to maintain pH at 7.2 to 7.6, total alkalinity at 100 to 150 ppm and calcium hardness at 100 to 275 ppm.
1. Before using Azure Stain & Scale Remover, adjust pH between 7.2 to 7.6.
2. For best results use Azure Stain & Scale Remover in the evening with pool pump and filter operating overnight.
