  • No phosphate By Michael on 7/29/2015

    Had a problem starting with bubble algae and one problem area with turf algae. Ordered and used this in a BRS reactor SUPRISE no more algae and no phosphate. Works great, just use less than recommended at first so you don't shock your system. Takes about 3 gallons of RO to flush fines and rust color from the water. Ordered more when I ran out and will continue to use it.
  • 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
