When your ready to setup your GFO reactor's performance this product will not let you down. I have this running in my Deluxe GFO reactor with MAXIJEt 1200. IMO BRS's recommendations are the best choice. Watch the videos on BRS, they are awesome.

This is hands down the most effective reactor media to control phosphate levels. It works out to be less expensive due to the absorption capacity.
incredible By Douglas on 5/3/2011

have used many phosphate removers. Non compare to the quality or consistency of GFO HCFO highly recommend Little pricey but performance and amount necessary outweighs the cost difference of competetiors products. Thanks BRS
does the trick By cocugreek5 on 5/1/2011

I had high phosphates around 1. This is the first gfo I have used and based on my present experience and those of others, I won't be changing anytime soon. That goes for the gfo as well which holds up well and the water out of the reactor is still less than the tank itself after 2 weeks. Keep in mind this is the first time I ran a phosphate remover in the 6 years of the tank. The hc gfo is great for these situations where there is real severe phosphate problems. It does great in a single reactor and perfect if your tank is under 125 gallons. With the regular gfo and lets say a 150 you would have to go with brs' jumbo reactor. I wish it was cheaper but you get what you pay for.
Best GFO Out By Scott on 4/30/2011

This stuff really works my phosphate was at 0.83 and it dropped it over night to 0.24 that is really a sign that this product really works. I have used other products and nothing ever came close to this. A little expensive but this goes to show you you get what you pay for!!!!

Now that my tank is established and I'm slowly introducing different livestock I noticed that the zoanthids stopped opening up. I read online and the blogs were saying that high phosphate levels in the water would stop the zoanthids from opening. I purchased 3.5 Pounds Bulk GFO High Capacity Ferric Oxide and a reactor from BRS and within a week of having the GFO filtering the water the Zoanthids started to open. Now a month later the Zoas are in full bloom and look amazing.

I have used many GFO products, and this one seems to hold its own. I do not have to change the media in my reactor nearly as often to keep low phosphate levels in my tank with this product. Buy in bulk and save!
Working like it should! By June on 2/19/2011

Purchased this for our 180 gal SPS dominant/fish heavy aquarium along with the Hanna meter. Added in 1 C of this stuff to our Warner Marine reactor (BRS calculator rec'd 1.44 C) but I wanted to start low so as to not freak out the corals. In about 36 hours, PO4 went from 0.58 to 0.26. Any small amounts of red cyano or green that were on the rocks or glass are going away! Going to up the dosage today or tomorrow to get ALL the PO4 outta there! Wonderful product. I have tried Two Little Fishes before, and it worked OK, but I think this product is so much better and for the price/amount you get, you can't beat it. Going to add it to our 24 gal JBJ nano as a precautionary. Thank you BRS!!
great product By Chu on 1/19/2011

I personally found GFO HC is better than regular GFC. With the same amount, it seems to get rid of the cyano I have, while regular GFO just stop the cyano from spreading but not totally destroying it.
Allowed me to avoid having to use a Jumbo reactor... By Loknar28 on 12/6/2010

I wasn't sure about using this instead of the regular GFO, but when you figure that you only have to use half as much it is worth the price difference. According to the reef calculator I would have had to use almost 4 cups of the regular stuff for my 240G. So I decided to get the HC GFO with a deluxe standard size reactor instead of the jumbo. Also the fines seemed to clear much quicker.

Works great. Quickly lowers phosphate levels, and isn't messy.

I used to use Rowaphos which worked great. However for the price and performance Bulk Reef Supply high capacity GFO works better in my reactor and last longer and is cheaper that Rowaphos. Will never go back to the more expensive stuff.
