Pyrolox filter media comes in 60 pound bags.
Great at reducing iron, sulfur, and manganese from water. You only need to backwash with this product. A naturally mined ore, Pyrolox is a mineral form of manganese dioxide, which has been used in water treatment for more than 75 years. It's a granular filtration media for hydrogen sulfide, iron and manganese reduction and functions as a catalyst, but itself remains relatively unchanged.
Pyrolox works in a principle whereby the hydrogen sulfide, iron and manganese are oxidized and trapped on the media while simple back-washing cleans the bed, No chemical regeneration is required, nothing is imparted into the drinking water and has a high capacity for low contaminant concentrations.
