  • Amazing Product By on 1/10/2017

    Noticeably helps with algae almost immediately
  • Good By on 12/17/2016

    Change GFO monthly. I can tell by looking at the algae in my tank if I am late doing the change.
  • Great GFO! By on 12/16/2016

    I've installed a reactor a while ago and have been using different media to filter out the phosphate. This however, hands down, is the best media I've tried.
  • Still the best By on 12/13/2016

    While the HCGFO is better, you still can't beat the quality and price of regular BRS bulk GFO.
  • Great product By on 11/6/2016

    I would highly recommend this product. It helps with keeping algae in check and off your Aquarium glass.
  • Great value By on 9/15/2016

    Will definitely order again
  • Another home run for BRS By on 9/5/2016

    I was using Two Little Fishes phosban whatever stuff, it's too fine of a material for my taste. So I switched to BRS's GFO and I am very pleased with it. It comes in larger containers and it's cheaper.
  • Works Great By on 8/24/2016

    Good value, & quality
  • This stuff really works! By on 8/8/2016

    This product really performs when used in a reactor and will last at least a month in my 91 gallon system. My phosphates are no longer a worry for this reefer!
  • Awesome product By on 7/28/2016

    I should have installed a reactor a long time ago.
