Granular Ferric Oxide is a popular means of reducing and maintaining low phosphate levels in your aquarium. There are many sources of phosphates in your aquarium. They can come from your base rock, fish food, or any other organic matter that enters the tank. They are a leading cause of algae problems, including diatoms, hair algae, and cyanobacteria. GFO removes phosphate by molecular bond and will not leach them back into your water when exhausted. The most popular and effective implementation method is with the use of a fluidized reactor. Use a flowrate through the reactor just strong enough to keep it gently tumbling. This will help prevent clumping and channeling of your GFO media. The other method of use is by filling a media bag, and placing in a high flow area of your sump, or filter compartment.
