Directions

Pre-Treatment:

1. If swimming pool is equipped with a heater, first turn the heater off, then isolate from the circulation system

2. In order to prevent damage to swimming pool, do not allow undissolved product to sit on surface for more than 30 seconds 

3. Swimming can resume as long as the chlorine or bromine residual is between 1-4ppm and the pH is between 7.2-7.6

Treatment: 

1. Adjust balance of pool water to the following:  pH 7.0-7.4, total alkalinity 125-150ppm ( or 80-150ppm for pools equipped with a chlorine generator), calcium hardness less than 400ppm 

2. Adjust chlorine or bromine residual to less than 1ppm. Use BioGuard Chem Out if necessary to reduce the residual of chlorine or bromine. For SoftSwim pools, maintain SoftSwim B residual between 30-50ppm. Do not add a shock product to the pool water during this process otherwise re-staining may occur

3. Wearing safety goggles/glasses and with the circulation pump running add 1.75lb of BioGuard Erase Iron Stain Remover per 10,000 gallons of pool water. If stain is specific to one area, apply the product to that area. Use surface compatible brush to brush away undissolved product off of the pool surface

 4. Allow the pool water to circulate for 1hr. The apply the proper dosage of Pool Magnet Plus ( or SoftSwim Stain Control if treating a SoftSwim pool) per label directions. This will help prevent the metals from re-staining

5. Allow pool water to circulate for 24hrs

6. Apply BioGuard Sparkle Up (or SoftSwim Filter Aid for SoftSwim pools) to cartridge and sand filters per label directions for filter type and size

7. Continue to circulate the pool for a minimum of 24-48 additional hours

8. Remove BioGuard Sparkle Up (or SoftSwim Filter Aid for SoftSwim pools) from filter by backwashing or cleaning cartridges

9. Apply BioGuard Kleen It (or SoftSwim Filter Cleaner for SoftSwim pools) according to label directions to remove any metals trapped on the filter. Complete stain removal may take up to two weeks or require a second treatment

10. Test pool water and adjust water balance items and sanitizer to the following:  pH 7.2-7.6, total alkalinity 125-150ppm ( or 80-150ppm for pools equipped with a chlorine generator), chlorine, bromine or SoftSwim to residual specified on your sanitizer product. For SoftSwim pools, re-establish clarifier level to 30ppm

11. After completing steps 1 through 10 prevent stains from reoccurring by using BioGuard Pool Magnet Plus (or SoftSwim Stain Control for SoftSwim pools).

12. If necessary, a repeat treatment, starting with step 1, can occur if stains are still present 48 hours after completion of step 11
