BioGuard Pool Magnet Plus is a concentrated chelating agent that ties up metals (iron, copper, and manganese). This product removes fresh stains and prevents staining due to metals. Use this product monthly for swimming pool with metal-containing fill water. This product should be used in chlorine or bromine treated pools only.

Directions

Read the entire label and use strictly in accordance with precautionary statements and directions.

Prevention of Stains

To treat for metals in pool water, backwash filter, then allow pump to run continuously during treatment. If the total amount of metals present exceeds 1.0 ppm, also use BioGuard Sparkle-Up Filter Aid to assist in metal removal. Use 1 quart of this product per 10,000 gallons of water per 1.0 ppm of metals. Maximum recommended dose is 3 quarts per 10,000 gallons. Add directly to the pool in the area of any localized metal stains. Some temporary clouding may occur. Clean or backwash filter as indicated by pressure build-up. Never allow filter pressure to exceed the limit established by the manufacturer.

Maintenance Dose

When make-up water contains metals, add 3 fl oz of this product per each 1,000 gallons of water added to the pool.

Removal of Fresh Stains

Many fresh metal stains can be removed by the action of this product. Turn circulation off for 8 hours. Slowly, and as close to the surface of the water as possible, pour one to three quarts (depending on severity of stains) of this product directly in the area of the stain. Do not swim or operate pump for 24 hours. After the waiting period, turn the pump on, circulate water continuously for 5 to 7 days and brush pool daily. Use BioGuard Sparkle-Up in the filter to remove re-dissolved metals. Repeat treatment for large metal stains. For white plaster pools where large metal stains have aged into the pools surface, draining and acid-washing is recommended.
