Robelle 1-Quart Super Mineral and Stain Erase, Pool Metal Remover, Stain Remover, Made in USA

This product is specially designed to chelate complex minerals that naturally occur in some water supplies. Minerals, such as iron or manganese, can cause stains and discolored water. Water that has been pre-treated with this product can avoid problems that can arise from the reaction of iron or manganese with subsequent additions of chlorine or shock treatment. This product is concentrated and ready to use. This product will not interfere with chlorine, algaecides, or stabilizers. Add separately and do not mix with other chemicals. When used regularly, this product will help prevent scale build-up and mineral precipitation caused by other chemical additions. New Pools or Pool Opening: To prevent discoloration of the pool water due to trace amounts of iron, manganese, and other heavy metals, add 11/2 oz. for each 1,000 gallons of pool water. This addition should be made before any other chemicals are added. Recirculate the water, to insure uniform distribution, before proceeding with other chemical additions. Discolored Water: Have your dealer determine if the discoloration is due to iron or manganese. If the water contains less than 1 ppm of these materials, add 11/2 oz. for each 1,000 gallons of pool water. If the water contains greater than 1 ppm add proportionately greater amounts. Test the pH of the water, after addition, and adjust to 7.2-7.6, as necessary. Recirculate the water to insure uniform distribution. Scale Build Up: Scale build-up is due to high levels of calcium and other hardness minerals. Add 3/4 oz. for each 1,000 gallons of pool water and recirculate for at least 6 hours after addition. To prevent a recurrence of scale build-up, add 1-2 oz. for each 5,000 gallons of pool water each week.
