How To Use

Prevention of Stains:

  1. Backwash the filter, then allow the pump to run continuously.
  2. Apply 1 quart of Pool Magnet per 10,000 gallons for every 1.0 ppm metals. Maximum recommended dose is 3 qts. per 10,000 gallons. If staining is present, add product directly over these stains.
  3. If the total amount of metals present exceeds 1.0 ppm, apply Sparkle Up Filter Aid 48 hours after Pool Magnet addition to assist in metal removal.
*Temporary clouding may occur upon addition.

Removal of Fresh Stains:

  1. Turn the circulation pump off for 8 hours.
  2. Slowly and as close to the surface of the water as possible, pour one to three (depending on severity of stains) quarts of Pool Magnet Plus directly in the area of the stain.
  3. Do not swim or operate pump for 24 hours.
  4. After the waiting period, turn the pump back on to circulate the water and brush the pool for 5-7 days.
  5. Use BioGuard Sparkle Up in the filter to aid in the removal of redissolved metals.

For white plaster pools (only) where large metal stains have aged into the pools surface, draining and acid washing is recommended.
