  • Great Filter and A+ for service By Noe on 1/7/2016

    The container was damaged in shipping and BRS replaced it without any hassle. As for the media, I use it in my AIO to keep algae under control. Awesome filter

    I had a problem with Phosphates in my reef tank until now....Thank you BRS for this life line that makes it possible to have excellent water quality. You guys are the best and so are your products.

    I use the GFO in the BRS dual reactor with carbon. Works wonderfully! Would definitely recommend it to anyone looking to control phosphates.
  • very fine like powder. By Sean on 11/2/2015

    Works good at keeping phosphates down. I don't like how fine it is. Some can make it threw filter.

    Working just like it should. don't know why I didn't do this sooner.
  • Seems good. By clockman on 10/9/2015

    Like the title says. Seems like it does the job. I don't bother measuring phosphate in the water. I'm a bit lazy.
