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.

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

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.

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

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.

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!
