EFC Pool Stain and Iron Remover

A multipurpose granular cleaner which removes iron, stubborn oils, grease, hair and debris from DE filters and the surface of full pools. Very effective in removing unsightly stains from swimming pool surfaces. Cleans pools, filters, spas. No need to drain or acid wash.

Recommendations for Stain/Iron Removal Using EFC

1. DOSE: Use 15 pounds per 20-80 linear feet of wall depending on the severity of the stain.
2. Try to lower chlorine the chlorine level to about 0.0 ppm.
3. Turn off circulating pump(s) and chemical feeder pumps.
4. Add 1-2 ounces of Problem Pools per 1,000 gallons of water to keep the pool from turning cloudy.
5. Carefully, pour (sprinkle) the EFC along the walls of the pool all the way around and as close to the edge as possible. Use wall brush to break up any lumps that fall to the bottom of pool. Lumps of EFC could temporarily stain the pool purple.
6. Save a couple of cups of EFC for cleaning the filter after using EFC on pool.
7. Wait ½ hour to several hours for EFC to clean surface. Then proceed with the filter cleaning: While backwashing; add the 2 cups of EFC to a skimmer, backwash for at least 3 minutes, rinse the filter and restart the circulating pump.
8. Add 1 pound of soda ash (pH-Up) for every pound of EFC. Wait 15 minutes then test the pH; if under 7.5 add more soda ash. Try to keep a pH of 7.5 to 7.8 for several days.
9. Add 1 pound of Oxy-Brite for every pound used of EFC. Note; if a purple cloud appears after adding the EFC you may need to add more Oxy-Brite to help clear the pool. It may take several hours for the purple color to disappear.
10. Start adding chlorine slowly until reaching a level of 1.0 ppm. If you raise the chlorine too high, or too quickly, you risk restaining the pool. The pool is now ready to reopen. Maintain a low chlorine for a couple days to prevent re-staining.
11. Add a sequestering agent such as Sequa Sol. Use a sequestering agent weekly or when you add water to the pool to prevent iron stains.
