nice and clean. I use in my reactor. With other brands took like 15 gallons until clean and clear water was following. With this high capacity only takes like 5 gallons to run clean. Love it and would recommend for all phosphate issues. Of course you cant beat the BRS service and price.
Best way to keep my phosphates low By Michael on 3/18/2014

I run this GFO in my 90 gallon mixed reef tank. Have it running in a 2 Little Fishes reactor and it works great. Replace every 4-6 months and my phosphates stay at zero. Highly recommend.

Running this with the ROX carbon through the BRS dual canister (one in each chamber) and I am shocked by the phosphate removal in less than 3 days.
Before running, our phosphate was 1.3 ppm in the Hannah meter. I am running less than recommended by the BRS calculator only because I didn't want to completely shock the system. However, after less than 3 days it's down to 0.03 ppm. Wow! I'm going to continue testing in another few days to see if it drops further. If not, I will bump up to the recommended level. Thanks, BRS for another couple of great products! Worth the price!

I'm running the GFO high capacity with an IM Minimax reactor on my nuvo 24 tank. I was getting some nasty hair algae after trying to fatten up some new fish. PO4 was around 0.08 and that was with Chemipure Elite in the media basket. After a few days by phosphates went down to 0.03 and last night I registered 0.00 using the Hanna low range checker. CUC is destroying the algae now and it take about 3 days before I get a noticeable green/brown film on the glass.
This seems to be a great value. Given the size of my tank and the rate the GFO is being used up, this is pretty affordable way to control phosphates. I highly recommend.

Works great at controlling phosphates. Also, works well in a media reactor as I use it with the TLF media reactor with a maxi-jet pump.
Must have for any reef tank By James on 1/24/2014

I've been using the brs standard gfo and this gfo makes a huge difference. I couldn't keep my phosphate under .06 with the standard stuff. Now I've got it down to .01 in only the first week of using this product! I'm very happy even though it's a little more money.
Must buy! By devon on 1/9/2014

i really love this media, i have seen drastic changes while using this. i tends to last long than the cheaper stuff. less dust is a big plus. i must say though what until it is on sales thats when i order it.

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
terminator would recommend this product to a friend
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.

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.

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).
