  • You know, Gfo. By Vegareef71 on 5/24/2015

    Brs Gfo is affective and very easy to use. Just follow the instructions on the container or hit up BRS online and the calculator with help you out.
  • Worth it By Sosee on 5/21/2015

    a good value but don't use the amounts they recommend in the reactor. I followed the advice of a seasoned reefer and used half the recommended amount and it works great! Using too much can effect your alk levels.
  • great By wiz on 5/20/2015

    I'm assuming by my lack of green dlime and hair algae it has worked as promised. Thanks
  • It really does mean granular By James on 5/13/2015

    I've only had the GFO in for about a week now but I've been testing every day (too much time on my hands) and my phosphate level is definitely on its way down. Not enough time yet to say anything about the algae, but science doesn't lie. I only have one thing, filter socks don't work with this. I put it in and started to rinse it out and it started coming out of the sock like dust (which it is). But that's my lack of experience, not the product.
  • A must for reef By Deafclown on 5/6/2015

    I wish I had used this in the beginning! I believe it's a must have for a reef to help keep phosphate down and calm the algae growth.
  • great By fernie on 5/5/2015

    this gfo worked great on the phospate and controlling the algea problem
  • works By Jack on 5/3/2015

    mix with carbon and it works in my setup
  • good clean dry product! By jon d on 4/21/2015

    Been using this stuff in a reactor for a wile now. I guess it works.
  • Great stuff! By Shery on 4/3/2015

    This stuff rocks! Keeps my phosphates at 0. I change it once a month, though I am sure it would last longer if I left it. Never hardens or clogs. Love it!!
  • PRICE AND QUALITY By machote on 3/27/2015

    very good product i used to run a ATS (alggae turf scrubber) it was great but so much evaporation and maintenance needed each 7 days, also you need to design it very well and do a lot of research ( i spend a lot of hours? a lot of $ on light because u need a watt for gal now imagine in a 300 gal reef tank, also water splash etc, this gfo does the same but less work so then this is GREAT no maintance needed just replenish each month or month and a half
