## Customer Reviews

### ⭐⭐⭐ 







  
  
    Irregular granule size leads to more waste than usual for GFO
  

*by C***D on Reviewed in the United States on October 13, 2014*

I've ordered this same GFO from BRS in the past without issue. This time decided to grab it through Amazon Prime to save on shipping. Unfortunately, any savings in shipping have been mitigated by having to toss/filter out about 25% of the contents because the granule size was too fine. It looks like the container was either shaken vigorously for an extended period of time, or was perhaps a QC oversight. I've used GFO from TLF, BRS, and even phos-x, in all instances, the granule sizes were far more uniform than this batch of GFO.It seems to work the same as my last batch of GFO from BRS direct, but the added pain of sifting out all the fine particles (more so than usual with GFO) and the loss of usable product due to granule size makes this a losing deal compared to past experiences.

    Awesome!
  

*by J***Z on Reviewed in the United States on July 2, 2013*

I was buying expensive pre packaged products for way too much $$ and was getting inferior results. Buying this in bulk and mixing with their carbon has completely changed the way my reef tank looks. No algae or diatoms on glass for DAYS! I mix in a mesh bag with their carbon. Only a small amount is needed.

    Love this stuff

Amazing!!!! Put this in my Phosban reactor it has basically removed all the phosphate from my tank in a few day.  Decreased my phosphate by 90% in 4 days
