  • 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

  • great stuff By donthavta on 3/7/2015

    I was watching Mr Saltwater Tank on u-tube ,he turned me on to bulk reef supply. I was having a big algae problem . He said to use BRS bulk Gfo in a reactor .The algae was out of the tank in 3 day /with light out . Wow this is the best my 15 year old tank has ever looker. Also it was a great price and was shipper very fast. Will buy all my need from BRS
  • incredable By ttboys on 2/15/2015

    wow this gfo works fantastic .I had quite a algae problem going ,but in one weeks time have reduced to almost none at all
  • Excellent By luis on 2/15/2015

    This works very well and I have only been using my gfo from brs. Very straight forward I run mine in a canister along with brs carbon in another canister I simply fill, install open my ball valve and rinse with tank water until dust particles at minimal or just until water comes out clear so it helps with a 1-2 gallon water change in my total 90g reef. Also I only have to change it every month and a half to two months on my bio load very good. Thanks BRS!
  • Good Stuff By Chris on 2/13/2015

    Started using this GFO in a BRS single reactor mixed with Carbon after having a green dust algae bloom in a newly established reef. I noticed differences the next day. Removing the phosphates completely killed off the algae within a week. Thanks for the advice BRS, good media!!!
