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.

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!
