Working like it should! By June on 2/19/11

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!!

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 12/6/10

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.

Best Phosphate removal By Joshua on 10/26/10

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.

This product does an astounding job of eliminating algae problems and lowering phosphate levels. Quick and easy product. I threw a cup of this product into the BRS Dual Reactor and the rest is history. Well worth the money.

Good product but pricey. By Rak on 10/19/10

HC GFO is good stuff. It does lower phosphates. It is pricey but your corals will reward you with good growth.

When I first saw this product, I thought "pricey!". But don't let the price scare you. This is a much better value than your local fish store's GFO. Last longer and preforms better. Need I say more?

works great By Matthias on 9/23/10

Prefer this over the lower capacity gfo due to having to use asmaller Amy in my reactor. Phosphate is at zero.

I use to use ROWAPHOS GFO until I found out it is the same at the BRS High Capicity GFO. Thanks BRS for saving me lots of $$$$.

YOU GET WHAT YOU PAY FOR! By TOMMY on 9/13/10

TOMMY would recommend this product to a friend

My dad always told me YOU GET WHAT YOU PAY FOR, and yes this is one of those products thats may cost more then the typical phosphate remover but this works wonders, i swear i have a huge tank and barely do any water changes and its all because of this BRS HIGH CAPACITY GFO, even when i think i went to long with a water change I check my levels and they are still at zero! This is an unbelievable product that i believe is a must have for anybody with a reactor!

Overall great product, cost is a little high for quantity though By gsago1979 on 8/18/10

I was very happy with the overall performance of the GFO media in my BRS reactor. With in a few short hours I noticed a difference in my tanks overall appearance including polyp extension and general water clarity. With in a few days I noticed a decrease in algae build up on the glass and a reduction in algae on newly established live rock.

Definitely a satisfied customer on this product but in comparison to the other GFO products Im not sure on the higher price level. It seems quite a bit higher than the other granules but I have not had the oppurtunity to sample the differences yet to truly evaluate the cost/qty/performance benefits.

Great stuff!!! By Jorge on 6/16/10

For me, this high capacity GFO really does last twice as long as regular the regular GFO. This allows me to change it every two months instead of monthly on my 210g reef system.

I first bought 1.75 lbs since I was not sure what kind of results I would see, results = GREAT now I just bought 7 LBS. That should keep me stocked for a while!

Low dust and quick to drop phosphates. I used the HC GFO in a media reactor however my brother uses in media bags. Both work great!

This is my second order of BRS High capacity GFO and my 20 and 58 look so good I started a 125. Bulk Reef Supply makes everything so easy and affordable.

Yes it's pricey but worth every gram!! You can't go wrong with this high capacity GFO! Awesome products, great prices, fast shipping and you get what you order!! Thanks BRS and keep up the fantastic Quality and Prices!!!

This GFO is very nice!! By charles malek on 4/16/10

charles malek would recommend this product to a friend

I just bought the one gallon to try it out. I'm impressed already. While rinsing, this GFO isn't like others. There is WAY less dust and fines that come off it. The rinsing water didn't turn a thick brownish red color like it does with other GFOs.

I don't have issues with PO4 right now, so I'll repost later. We'll see how good this HC GFO works at keeping PO4 low (I'm sure I will good success with it).

Rinses clear very quickly and much less dusty and grainy solid than the regular stuff.

I run the HC GFO in a single BRS reactor and it is a definite phosphate killer always keeps my phosphates in check.I have ran other GFO brands but I must say this one is the best out there.

Much more dense than most GFOs. Little dust and if used in moderation, can be mixed with ROX.

The best bang for your buck!! By Jeff Greene on 3/5/10

This media is the best out there. Why would you not get the HC ferric oxide. It does double what all the other ferric oxides do with less media. I have already noticed that there is less algae on the glass.
