BRS Bulk GFO Granular Ferric Oxide - High Capacity

  • I'm sold, will never run without it. By Bruce on 12/14/2014

    Was having phosphate issues on my 90g mixed reef tank so I thought I'd give it a try after reading the other reviews....they were right! I am running a BRS single reactor and mix about 1 part High Capacity GFO & 2 parts BRS Premium ROX Carbon. After a week I was convinced my Hanna Checker was broken because it kept coming up 0 phosphates...there was nothing wrong with my Hanna. Been using this about 6 months now and have had no phosphate issues or no ill side effects. I didn't think I really needed the carbon but carbon is cheap and has it's benefits, and with the mix you don't have the hassle of tweaking the flow to try to maintain the right amount of tumble.
  • BRS BULK GFO-High Capacity By mt88 on 12/13/2014

    after 2months battle with algae, system running with algae scrubber, refugium, large protein skimmer, with all that running I decided to install and use this product, never thought it would work but after 5 days came back from vacation things really improved and all my sps corals starting to look happy and fish get to eat a little more food.
    Thank you BRS!
  • Great Product By Evelio on 12/9/2014

    I have used several different types of GFO products and this one gives us the best performance vs cost
  • 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.
  • Does its job, works good both in my wallet and in my tank By DOMINICK on 8/21/2014

    Does its job, works good both in my wallet and in my tank
  • 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!
