Nava Stain & Scale Remover is best used for metallic stain removal and prevention of hard water scaling. It sequesters the material causing stains and scale and holds them in solution. If stains persist, they may be old stubborn buildup that requires complete cleaning of the walls. Dissolved metals and minerals (such as Iron, Calcium, Manganese, and Magnesium) in pool water and corrosion of metal pool fittings will often cause staining and/or scaling. pH below 7.0 will cause water to become acidic and cause damage to Pool Heater heat exchangers. For scale prevention, it is also essential to maintain pH at 7.2 to 7.6, total alkalinity at 100 to 150 ppm, and calcium hardness at 100 to 275 ppm.
Stain Removal:- Before using Super Rust & Scale, adjust pH between 7.2 and 7.6

Stain and Scale Preventative Maintenance
- Follow all steps outlined above for Stain Removal
