    Excellent product
  • Works Great By on 4/20/2016

    I have been using this GFO for about a year now. I use it along with the ROX carbon on all my tanks. I have had great results from it and see no reason to change what works. I did try the high capacity one when this one was on back order a while ago and I did not see a big difference on performance. Then again my tank is very stable I should not see that much of a difference. I do change it every month along with the carbon so I don't get to push it to its limit. It is not expensive so I see no reason to push it. On occasions it has run for longer than a month as I have been away on business and my readings did not change so it does last longer than the month.
  • Drops PO4 fast By on 4/19/2016

    Thoroughly love to watch our PO4 go down to near zero/zero. We need to feed frozen food 2x a day and this helps to keep our PO4 in check!

    this keeps my phosphates down, i change this in my Reactor about every 4 to 6 weeks been using this for years

  • Only BRS GFO By on 3/28/2016

    All of my media purchases have been through BRS, and I would have it no other way. Price combined with great packaging, make this a no-brainer. I can't imagine a system without GFO, and BRS has it down.

    This is a great product.
  • Really works By on 3/21/2016

    Works Great at keeping my phosphates low. Easy to use in my reactor. I mix it with carbon using the recommended ratio. I use the standard granular because I change it more often anyway, because of the carbon loosing its strength before the GFO. If I was running GFO by it self I would get the high capacity.
