High Capacity Granular Ferric Oxide (GFO)
High Capacity Granular Ferric Oxide (GFO) is a very pure form of Ferric Oxide that will absorb phosphates and silicates in your aquarium, without leaching any contaminants into your tank, like aluminium-based phosphate removal media can.
With almost 4X the capacity of standard GFO, our High Capacity Granular Ferric Oxide is more cost effective and needs to be replaced less often, saving you time and money.
