BRS Bulk GFO Granular Ferric Oxide

  • 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!
  • AWESOME! By Stephane on 5/23/2014

    I had problems with phosphates and every product i used temporary lowered my levels for only a few days, and even then only had them down to 0.04. I decided to order this product along with the BRS reactor and i am not disappointed. I had this stuff in for about 1 week and on the 2nd day, i had 0 and i mean 0 phosphates!

  • gfo By alfredo on 5/19/2014

    great stuff definitely lowers ur po4sl
  • Great product just dusty By Christopher on 5/12/2014

    I have used this GFO for a few months now and have had no issues other than the typical dust that comes with all gfo products. I just run 2 gallons of ro water through it and have no complaints!
  • Great product that does what it says By Eric on 5/7/2014

    This stuff is great and absolutely reduced my phosphates. I've also used the high capacity. The bulk gfo does clump quite a bit and produces dust. I buy the high capacity now with no problems. Great stuff though.
