This gfo took my phosphates from .5 to undetectable . Amazing stuff now my corals are way more colorful and polyps are fully extended. Couldn't be happier with this product.
Excellent fast phosphate killer! By George on 12/28/2013

BRS' standard gfo is amazing... but this... this takes it to another level. My square 60 gallon salt tank was fill to the bring of slimy green algae. My brother then took this stuff... put it into my two reactors i recently bought and within a week the green disappeared. After 2 months, the water has remained crystal clear. The best time to get this is during their sale which is what we did during their black friday sale. Can't go wrong. Double the power of the standard stuff no joke!
GFO that makes a differemce By terminator on 12/2/2013

I have used many different types of phosphate removal products and for cost, quanity and effectiveness you can't beat the high capacity version of this GFO. There are a few other products that are as effective but cost more and you get less of it. Why spend more?
This is the only practical GFO to use, hands down
Tank is looking better after only days By Geo on 11/20/2013
Geo would recommend this product to a friend
Our LFS ran out of RowaPhos and it was going 3 weeks, I tried other gfos but they didn't do it, too much dust or they would just clump and not tumble, gave the high capacity a go and my tank is already looking better. I believe I will be sticking w this from here out.

Great Product By MICHAELO on 9/30/2013

Very well constructed and easy to change canisters, mounting option is cool. Makes use of space and utilizes 2 separate elements for individual change, Bottom line is, it makes life much easier! If you have a need for these elements then you have a need for this item.

By using this over the regular GFO I was able to mix with the ROX carbon and fit in one reactor.

Really brings down Phosphate levels By Chris on 7/15/2013
Chris would recommend this product to a friend
Before I bought my GFO reactor I had a terrible problem with nuisance algae, especially hair. A few of the CUC ate it but it was growing too fast for them to keep up with, even when reducing the lights to only about an hour a day.
I'm amazed at the difference the BRS GFO made once I started running it. It has completely controllled the phosphate levels in my tank from on average 14ppm down to 0.0ppm and no nuisance algae. It's reduced it so much that I now how to supplement nori for the algae eaters so they don't starve!
I'd recommend this for anyone who's serious about controlling their Phosphate levels.
Excellent GFO By Joe on 5/25/2013

Keeps my phosphate below 0.003 ppm or 0.032 microMolar, which is the limit of detection with the Hanna Ultra Low Range phosphorous detector (HI-736).

This was recommended for my algae problem and I was sick of trying different things and them not working. This is pricy but you get what you pay for, works great!

I have used both regular and HC GFO. I went with the cheaper regular last time and have regretted it. I highly recommend this product it lasts longer and requires less product to sufficiently do the job.

Helped remove all the hair aglae in my tank By Justin on 4/1/2013
Justin would recommend this product to a friend
I have used this twice on an off over a number of years, I had a pretty bad hair algae issue and I tried everything, after months of extracting and using phosphate removal stuff, I couldn't get rid of the algae. After adding this back in it took a little while, though no more algae.
I still get the green hue on the glass, though it takes longer now before it appears.

I am using a brand new 6 stage BRS RO/DI unit with 150gpd upgrade and booster pump. Yet, I still get a light brown/green haze on the glass daily. I only feed frozen Mysid and Frozen Formula 1 every other day making sure not to over feed. With the exception of shrimp to the BT Anenome and and DT's to the corals. No hair algae or anything bad but that dang haze. Well Folks! No More! I added BRS High capacity GFO (by BRS Calculator) in the BRS GFO reactor and it was cleared by the next day! Actually it's been 3 days and I just went over the glass and really still didn't need it. Awesome Stuff! I only regret not adding this day 1.
Essential part of process to eliminate algae By Darcy on 3/7/2013
Darcy would recommend this product to a friend
I don't know why I didn't use this stuff sooner. Algae was growing faster than we could remove it. Instead of enjoying our reef tank it was becoming a burden. My phosphates were always on the high side but changing our feeding practices and adding cheato to the sump never seemed to substantially change the high readings.
I set up a reactor and added High Capacity GFO from BRS. The phosphate readings dropped markedly but the algae stuck around. It was less prolific and pale looking but it was still there. So, on the advice of a fellow reefer, we obtained a sea hare and let it go to work. After 3 weeks virtually all my algae was gone. We added a fresh batch of GFO to the reactor my readings stayed where I want them at about .04 and there's no resurgence of algae. It's been over 6 weeks with no trace algae and my corals have more color to them. Hopefully, we have this licked.
When I consider all the work we went through prior to this I don't know why we dragged our feet implementing GFO to our system. BTW, no sea hare was harmed in the removal of the algae. Once there was no more algae to consume our LFS gladly gave us store credit for the returned sea hare.

Need to get your phosphates back in check? This is definitely a fix then. The key to using this GFO is to be regular in changing it and the correct flow through your reactor. A light wave in the surface of the media and changing it out after about 2 weeks works wonders for my tank. Thanks BRS for another great media!
