BRS Bulk GFO Granular Ferric Oxide

  • 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.
  • Performs well - But needs to be rinsed Very Well By Alex on 7/19/2014

    We used the High Capacity GFO first and it worked great. This time we decided that since we had a large reactor and plenty of space, we could use the GFO that wasn't as compacted to be a little cheaper . It worked for its primary purpose - get the phosphate out. It's just that we had to rinse it with several gallons (5-10) of water to get the dust out and it still left orange dust on the bottom of my sump. I think we will go back to the high capacity stuff after we go through this batch.
  • top notch phosphate removal By swseipel on 7/6/2014

    This has been a great asset to my water treatment system removing phosphate due to my overfeeding my tank
  • Low phosphates! By James on 7/1/2014

    Cleans the water like it says, put it in a reactor and let it work
  • Works Great By Christopher Kirkland on 6/25/2014

    As always works very well, and lasts a long time. Keeps the algae at bay and the PO4 down to levels my SPS like.
  • Lower Phosphate Levels! By Vincent on 5/25/2014

    Was experiencing Phosphate levels of .10 ppm set this up with the BRS dual reactor. After 24 hrs PO4 dropped to .05 ppm and after 48 hrs PO4 dropped to .01 ppm. Thanks BRS!
