BRS Bulk GFO Granular Ferric Oxide

  • a must By Christopher on 12/24/2014

    This works wonders if you follow the instructions. I've been running it for close to a year now, and it is a staple for sure. You must use the correct amounts, and you must change it out. Don't expect results if you are to frugal with it.
  • Good Product By Wade on 12/23/2014

    Been using a cup of this in my reactor for about two weeks and i can already see a difference in my tank. Algae is almost gone. Phosphates are virtually at 0 now. I will continue using this product as long as I have an aquarium.
  • It works like it should By Mark on 12/23/2014

    I've been using this in a filter sock in my hob filter. Although not the most efficient use of GFO it still does a great job of keeping my phosphates low. I only wish I had a larger setup so I could use a media reactor.
  • Good stuff, a bit dusty By Ryan on 12/10/2014

    Just make sure you rinse it well before placing it in the system obviously. It does contain a fair amount of dust, but does the job once installed. No complaints here, you get a lot for what you pay for.
  • for the price By justyn on 12/4/2014

    A great product for the price. I run gfo a long side my carbon and changing this product out gets expensive, once I found out about BRS I was hooked with them.
  • Excellent gfo for the price. By Roger on 12/3/2014

    Using this gfo has greatly helped me keep my p04 levels down to a minimum. Compaired to the expensive other brands it's crazy not to buy this stuff.
  • Good Prod By jawstone50 on 11/29/2014

    Increasing the frequency off my GFO changes has decreased the speed at which my Hair Algae problem has returned. I will keep this frequency pace to hopefully completely eliminate the algae problem all together.
  • Great product, great price! By Jdubs on 11/24/2014

    I run a 37 gallon heavily stocked with fish and LPS corals. This stuff removes phosphates FAST! Just make sure you use a reactor and don't just put it in a media bag you will never get the same results just running it in a media bag in a external filter. Keeps my reef looking pristine!
  • fair priced By mcbridepcm on 11/23/2014

    I think it's a very reasonably priced media, I'm happy.
  • Great product By Travis on 11/18/2014

    What can you say about this GFO? It works and at a great price.
