BRS Bulk GFO Granular Ferric Oxide - High Capacity

  • Great product By dolpator on 11/23/2014

    This is the only GFO that I use, it keeps my phosphates levels low to nothing. I use it with BRS media reactor with out issues. Great product would recommend it to any one needing g to remove phosphate in their systems

    I highly recommend this product. It keeps my phosphate levels ultra low.
  • superb media works better than promised By Bruce on 9/8/2014

    I'm running a 360 gallon reef/fish tank, have a couple of large 7-8" plus tangs, and an 8" queen angel, plus some smaller fish
    been having elevated phosphate levels, tried other reactors with no real effect,

    bought this BRS Jumbo reactor, filled it with the recommended 6 cups of GFO hi capacity and VIOLLA within a WEEK, my phosphate levels dropped from a .90 average, down to a .20 average.... a nice decline about .10 each day.

    This media REALLY does the trick

    HIGHLY recommended by

  • Wouldn't be without it. By Gerry on 8/21/2014

    I used to suffer from high phosphates and had unsightly hair algae growing. I tried water changes and scrubbing rocks. I finally tried GFO which worked well, but was messy to work with. I decided to try the high capacity and I will never use anything else again. This stuff is awesome and is very clean to work with. Hats off to BRS for this product.

  • Keeps PO4 in check By danny on 7/31/2014

    Very low dust unlike other types of GFO & you use less of it to achieve the same results which reduces stress on your pump. My PO4 levels are around 0.03 ppm using the HANNA CHECKER.
  • Best GFO on the market By Sean on 5/26/2014

    This is the best GFO I have used before. It lowers my Phosphates better than any other product on the market. The corals have noticeably become more colorful as well. Good product!
  • Regular vs Hi-Cap GFO By Drew on 5/11/2014

    I goofed and ordered Regular GFO instead of the Hi-Cap that I normally order.
    YES.... there is a difference.... My Phosphate levels have reacted accordingly.

    I have double the PO4 than I normally have when using the Hi-Cap.

  • High Capacity GFO. By Śruba on 5/10/2014

    I would buy it again because this media works very well for me. Try it yourself and see what I mean.
    Thank you BRS.
  • Look no further! By MUSBFRANK on 4/30/2014

    Let's just say I had a serious phosphate problem and tried several other medias. I put the recommended amount of GFO in a nylon sock and pumped water through it with a powerhead. It's a 750gal reef tank and the phospates had soared up to 2.0, after putting the GFO I tested the water roughly 3 days later and they were barely detectable. Can't say enough about this stuff and I will never use anything else!
