ECO Metal Out is a sequestrant that helps prevent and remove copper stains from swimming pools, as well as other minerals and metal deposits. Metal Out works on all pool surfaces and when used regularly will help prevent new metal stains from forming.
FOR POOL OPENING OR REFILLING: To prevent discoloration of the pool water due to trace amounts of iron, manganese, and other heavy metals, add 11/2 ounces for each 1,000 gallons of pool water. This addition should be made before any other chemicals are added. Recirculate the water, to ensure uniform distribution, before proceeding with other chemical additions.
FOR DISCOLORED SWIMMING POOL WATER: Have your local pool supply 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 ounces 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 ensure uniform distribution.
FOR SCALE BUILD-UP: Scale build-up is due to high levels of calcium and other hardness minerals. Add 3/4 ounce 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 to 2 ounces for each 5,000 gallons of pool water each week.
