BRS GFO Granular Ferric Oxide Needs New Image All AI devices include smartGFO comes in two types: Granular GFO is varied in its shapes and requires the least amount of flow to tumble. Good for reactors. High Capacity GFO is twice as dense as Granular GFO, so twice as much material will fit into a reactor. It's extremely hard and has less dust to begin with. Fewer fines will be created during use and transportation. By volume High Capacity GFO will remove roughly twice the phosphate compared to Granular GFO. Best overall
