I'm sold, will never run without it. By Bruce on 12/14/2014
Bruce would recommend this product to a friend
Was having phosphate issues on my 90g mixed reef tank so I thought I'd give it a try after reading the other reviews....they were right! I am running a BRS single reactor and mix about 1 part High Capacity GFO & 2 parts BRS Premium ROX Carbon. After a week I was convinced my Hanna Checker was broken because it kept coming up 0 phosphates...there was nothing wrong with my Hanna. Been using this about 6 months now and have had no phosphate issues or no ill side effects. I didn't think I really needed the carbon but carbon is cheap and has it's benefits, and with the mix you don't have the hassle of tweaking the flow to try to maintain the right amount of tumble.

after 2months battle with algae, system running with algae scrubber, refugium, large protein skimmer, with all that running I decided to install and use this product, never thought it would work but after 5 days came back from vacation things really improved and all my sps corals starting to look happy and fish get to eat a little more food.
Thank you BRS!

This is the only GFO that I use, it keeps my phosphates levels low to nothing. I use it with BRS media reactor with out issues. Great product would recommend it to any one needing g to remove phosphate in their systems

I'm running a 360 gallon reef/fish tank, have a couple of large 7-8" plus tangs, and an 8" queen angel, plus some smaller fish
been having elevated phosphate levels, tried other reactors with no real effect,
bought this BRS Jumbo reactor, filled it with the recommended 6 cups of GFO hi capacity and VIOLLA within a WEEK, my phosphate levels dropped from a .90 average, down to a .20 average.... a nice decline about .10 each day.
This media REALLY does the trick

Wouldn't be without it. By Gerry on 8/21/2014
Gerry would recommend this product to a friend
I used to suffer from high phosphates and had unsightly hair algae growing. I tried water changes and scrubbing rocks. I finally tried GFO which worked well, but was messy to work with. I decided to try the high capacity and I will never use anything else again. This stuff is awesome and is very clean to work with. Hats off to BRS for this product.

Keeps PO4 in check By danny on 7/31/2014
danny would recommend this product to a friend
Very low dust unlike other types of GFO & you use less of it to achieve the same results which reduces stress on your pump. My PO4 levels are around 0.03 ppm using the HANNA CHECKER.
Best GFO on the market By Sean on 5/26/2014

This is the best GFO I have used before. It lowers my Phosphates better than any other product on the market. The corals have noticeably become more colorful as well. Good product!
Regular vs Hi-Cap GFO By Drew on 5/11/2014
Drew would recommend this product to a friend
I goofed and ordered Regular GFO instead of the Hi-Cap that I normally order.
YES.... there is a difference.... My Phosphate levels have reacted accordingly.
I have double the PO4 than I normally have when using the Hi-Cap.

Let's just say I had a serious phosphate problem and tried several other medias. I put the recommended amount of GFO in a nylon sock and pumped water through it with a powerhead. It's a 750gal reef tank and the phospates had soared up to 2.0, after putting the GFO I tested the water roughly 3 days later and they were barely detectable. Can't say enough about this stuff and I will never use anything else!

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!
Very Satisfied By Charlotte Reefer on 3/10/2014

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.

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.
