We purchase our Granular Ferric Oxide (GFO) directly from the manufacturer allowing us to offer it for a fraction of the cost. This is the same material imported from Germany for the aquarium industry.

GFO is primarily used to remove phosphates from your aquarium but will remove arsenic and heavy metals as well. By removing phosphates GFO aids in algae control and will encourage faster coral growth.  

High Capacity GFO is our premium GFO and comes with several distinct advantages over the other GFO's. HC GFO is able to remove roughly twice as much phosphate for the same volume of material. This means it will last longer and require less maintenance. The particles are extremely hard and even better then the Pelletized GFO at reducing the effects of water abrasion. HC GFO works very well in both a reactor and filter bag. If you are going to be using a filter bag with your GFO this is the preferred product.
