  • good stuff By johnny 5 on 7/5/2015

    Saw significantly less hair algae after about 2 weeks. Works for me.
  • Best GFO By Shawn on 7/4/2015

    One of the best ways to drop those nasty phoshate levels in a hurry. I honestly never tried another brand but I don't intend to if BRS keeps making quality GFO.
  • good stuff By peter on 6/25/2015

    pretty good stuff. works as advertised.
  • Works great By Ray on 6/11/2015

    Very important piece of the algae free puzzle.
  • Slightly larger pellets are awesome. By Turf on 6/7/2015

    The slightly larger pellet size has made it substantially easier to deal with in a filter sock or reactor the ones I've used in the past.
  • 5 stars hands down By troy on 5/27/2015

    Easy to use rinse in ro di or with water change water and good to go
  • 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.
