  • Makes a difference By on 2/16/2017

    I use it every month to help with algae control you can tell it works
  • Low phosphate levels By on 1/29/2017

    I really like this product. I use it in media bag in my aio sump and my levels have been low and barely any algae.
  • 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.

  • 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.
