Phosphate Adsorption Media for Fresh and Marine Aquariums

Granular Ferric Oxide commonly refereed to as GFO ideally suited for filtering out phosphate from the water column which promotes better coral growth and helps prevent algae outbreaks. This medias porous high surface area is not only ideal for binding phosphate but also silicate, arsenic and other water-staining compounds.


- Great for Up-flow Media Filters/Reactors
- High Capacity
- German Made Bayoxide
- Absorbs Phosphate
- Binds Silicates
- Porous Surface

Directions for use:

Rinse media briefly using RO/DI water until clear before use. Be careful not to stir or crush the media due to its fragile nature. Place media in a tightly packed media bag or preferably use an up-flow media filter/reactor. Slow flow is desired and be sure not to tumble the media. The suggested amount is 1.5-2 cups of media per 100 gallons.

  1. Very good GFO media Review by Kyle
    Product Rating:

    Comparable to many of the other name brand media out there. (Posted on 12/6/2016)

  2. Just as good Review by Marc
    Product Rating:

    I have used all the top name Granular Ferric Oxide, and the coral view brand performed and lasted just as long.
    If you use the right amount for your tank size, and also use a good quality reactor for the media you will notice a big improvement in water quality . I use to put the GFO in a filter bag when i first started my reef tank years ago.
    The media will not perform to its full potential no matter what brand you use. I would recommend this product to
    anyone looking for a good GFO at a great price.
