Does anyone have experience or knowledge of water filters using Katalox Light? It's being promoted as a new media "for the removal of Iron, Manganese, Hydrogen Sulfides, Arsenic, Uranium ... and fine Filtration of Water in One Process." So far, I've found only one major U.S. manufacturer of whole house water treatment systems that uses this media, so I don't know if KL is just coming into the market or if it's not effective. Moderate levels of iron from well water is what I need to treat. Thanks.
