Jack's Magic's The Blue Stuff gives pool owners a powerful stain remover designed specifically for plaster pools to control plaster dust, yet gives up none of its cleaning strength. The Blue Stuff is effective at removing copper, iron, and manganese from your pool water, and will work in even high chlorine environments without breaking down. This solution will prevent and remove stains from plaster, vinyl and fiberglass pools safely and quickly, saving you time and money.

The Blue Stuff does everything “The Pink Stuff” does and more. The Blue Stuff’s proprietary blend actually removes copper from the water. The Blue Stuff is also very stable in higher chlorine levels and can be used in many fountain and water feature applications. Dosage: Initially, add one quart (32oz.) per 10,000 gallons of pool water then 6-8oz. per 10,000 gallons of water per week for maintenance.
