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.
Awesome Product By Toby on 3/26/2013

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

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.

Use this in a BRS Reactor and it works perfect, i use less than the amount needed and it still keeps my phosphates down
Another great BRS product. By JABlacher on 2/3/2013

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!
Good but not perfect By John on 12/7/2012

Like most reefers, I use BRS because it's the best when it comes to a whole slew of aquarium parts/additives/equipment. The prices are right, the products are great, blah blah blah.
But I was/have been a little disappointed by this Ferric Oxide - High Capacity. The reasons being two fold...I think that there is a lot more dust and residue in the batch than can be rinsed out with a reasonable amount of water. The result is that your reef is cloudy for a day or two, and the skimmer pulls out what I'd consider to be A LOT of ferric oxide from the water column over the next 2-3 days. Some of you might be thinking "turn down the flow in the reaction chamber", but enough flow to make the ferric oxide tumble is enough to make the tank cloudy with the stuff (even after rinsing).
My second gripe with the product is that it forms itself into a solid block inside the reaction chamber that is really tough to remove. And the flow is not too low either because as I see flow going down I increase the power of the MJ 1200 with a valve and the stuff still forms a brick in the reactor.
Granted, like most things, it's cheaper to get it on BRS than say getting rowaphos, but I like this product better for my tank.
Still I gave 3 stars because it kept phosphates at 0, just the other two factors matter a lot to me. I know for a fact that it's not good for clams to filter ferric oxide out of the water. I almost lost a deresa clam because I didn't rinse my rowaphos once.
Much better than regular GFO By Aron on 11/29/2012
Aron would recommend this product to a friend
This is a much cleaner, longer lasting GFO than the other standard one that BRS offers. Yes it is more expensive but you get a lot more lifetime out of it and I think there is less tumbling that grinds the GFO particles into smaller pieces and eventually dust. Also out of the box after filing up the reactor there is less dirty water coming out of the reactor which is a plus.

I just started using this product. Easy to add to BRS reactor. Flushes quickly and doesn't have much fines.
Will review again after further use.

Although a bit pricy, the High Capacity GFO really does out perform any other Phosphate removal media i have used.
High Capacity Rocks! By Mike on 10/21/2012

The high capacity GFO is simply the best. Must less fines and easily flows in the reactor. Nice Phosphate drop as well.
