BRS Bulk GFO Granular Ferric Oxide

  • Great product By Travis on 11/18/2014

    What can you say about this GFO? It works and at a great price.
  • Outstanding quality GFO By KEM on 11/14/2014

    This is my second batch of GFO Granular Ferric Oxide from BRS. Fantastic results in removing Phosphates. Would recommend it to anyone wanting a good GFO product
  • BRS knows how to make a good product!!! By Matt on 10/30/2014

    This stuff is the best I've been using it for two weeks and the phosphates are down to near 0 I'll never run a tank without this and they're dual reactor !!! Once again an excellent product by Brs
  • Great for small applications By Randy on 10/30/2014

    If you aren't burning through two cups of GFO every one to two weeks, then this is a great product, bang-for-buck wise!
  • What can I say... By blert on 10/27/2014

    ...never though I would pay so much for a jug of pulverized rust. Maybe I shouldn't have sold that old car... Could have scraped it right off the bumper. LOL! Seriously though... It's good stuff and a decent price when compared to other products.
  • Good Stuff By Christopher on 10/14/2014

    Been using this GFO for over a year and it's good stuff. Keeps my phosphates in check with no problems. Lasts a decent amount of time before I have to change. A little bit of dust to wash out before starting a new batch. No issues with it breaking down as long as you keep the water flow moderate. Works great for me. Thanks BRS
  • Best GFO for the cost! By David on 10/2/2014

    I tried several other products that claimed to clear up phosphate issues but none of them compared to the amazing results I have seen using BRS GFO. It is of the highest quality and the results show it!. The only GFO I will run through my reactor!
  • Great deal By Orlando on 9/29/2014

    I used this mixed with small particle carbon in my reactor, and works perfectly.
  • perfect By Kevin on 8/23/2014

    works like all the other anti phosphate products at what seems like a quarter of the price.
  • Rinse it first By David on 7/30/2014

    I did my homework when it came to adding chemical media in my reef. I have no complaints with this GFO. My Phosphates levels are always nearly undetectable and no algea, just make sure you rinse well before use.
