Swim Best Stain & Scale Plus - 1 qt

Swim Best STAIN AND SCALE PLUS For Swimming Pools – Non-Phosphate Formula

Prevents & Controls metal staining and scale formation

Dissolved metals and minerals (such as iron, copper, calcium, and manganese) in pool water and corrosion of metal pool fittings will often cause staining and/or scaling. This specially formulated chelating and sequestration product does not contain any phosphate based compounds. It is particularly effective for overall water treatment when used in conjunction with Phosphate Remover. Stain & Scale Plus is compatible with all sanitizing systems including biguanide and salt systems.

Stain & Scale Plus is a proprietary formulation that is best used for metallic stain removal and prevention of hard water scaling. This product is used in swimming pools to reduce scale formation in pumps and pool heaters, to eliminate plugging of filters and to reduce iron and copper staining. It is also an excellent stain remover when used in conjunction with A+ Stain Remover or EZ Stain Away products.

Soluble metals can be inhibited from precipitation by sequestering/chelating agents that bind with the colored metal ion to keep it in solution. Stain & Scale Plus sequesters the materials causing stains and scale and holds them in solution. Regular use of this product helps keep pool water clear, the pool walls free of stains, and prevent corrosion of metal pool fittings. Use of Stain & Scale Plus as part of the pool maintenance program will result not only in the control of scale, but also in the removal of existing deposits. This product is also highly effective as a rust-control agent.

DIRECTIONS FOR INITIAL USE

• Maintain pool water in the pH range of 7.2 to 7.6, total alkalinity at 100 to 150 ppm and calcium hardness at 100 to 275 ppm. If pH falls below 7.0, serious corrosion problems may result.
• For best results, use Stain & Scale Plus in the evening with the pool pump and filter operating overnight.
• Add 32 ounces per 10,000 gallons directly to the pool or by premixing into plastic pail of water first. Dispense solution evenly around the pool with the system running. DO NOT pour into skimmer. Continue to run pump for at least 24 hours.

STAIN AND SCALE PREVENTATIVE MAINTENANCE TREATMENT

• After INITIAL USE, repeat application at the rate of 8 ounces per 10,000 gallons every two weeks.
• In pools with a known metals or mineral issue, dose at the same level of 8 oz. per 10,000 gallons on a weekly schedule.

WINTERIZING

• Apply at the rate of approximately 20 ounces per 10,000 gallons of water by evenly dispensing as described above.
• Allow pool to operate for a minimum of one hour to thoroughly mix the product into the water prior to closing.

Note: In hard water areas where calcium hardness exceeds 400 ppm, it is advisable to double the dosages listed above. However, DO NOT increase the dosages more than double for one application.
