I bought this when I bought my brs dual reactor because money was tight. It lasted about 3 months, If I would have had the money I would have bought the 2 pound jug. It got me going and I saw a huge differance in the amount of algae on my glass. It works great and I'm hooked. If you want less phosphates and a cleaner glass and overall aquarium run this stuff from the best company in the biz.. Way to go BRS all your products are great and awesomely priced. I'm a loyal customer. BRS all the way baby!!!

GFO is expensive to start with, but Bulkreefsupply is the best price I have found on the web. Very fine and tumbles easily. Works great to lower phosphate.
I Should Have Bought More By Grey on 8/24/2011

So I bought the BRS GFO Reactor and MJ 1200 (don't get me started on that piece) and set everything up. As I was setting it all up, I had someone else test my Phosphate levels which were .39 ppm. That night, because it was a new test kit, I tried out the test kit myself and the levels were .19 ppm. I was sure then that the other person just didn't use the kit correctly because this isn't supposed to be an immediate cure or anything. The next morning I tested again and the phosphate levels are 0.00 ppm. This stuff is great. I should have bought more so I wouldn't have to come back a few months to replenish my supply.

I used the HC in the BRS reactor in my 85 gal tank. Though it did take almost all my algae away it was hard to dial in the reactor with the HC. I was constantly having to dial it in. It could have been user error however i currently use the Precision Marine reverse reactor with the Granuller and it works great on my 185.
good value and performance By Christopher on 8/17/2011

I've used other products and found for the price you can not go wrong with this gfo. This gfo helped solve my phosphate problem and dropped my levels to 0 almost overnight. Use it in a reactor which works really well.
Great!!! By Bryan on 8/11/2011

I started using this product almost a year ago. Like many of us I started without using RODI I was using distilled water or Ozarka for topoffs and saltmix. Hair algae and Phosphates soon took their unwated presence. After using this in a Reactor and using the RODI unit from this site no more algae, or nasty CYNO
prefer the pellets over the granules By Lee on 8/10/2011
Lee would recommend this product to a friend
The granules need more care in controlling water flow and tumbing to prevent the agent from breaking down and entering the water stream. The pellets seem to be more mechanically stable for use in a reactor. Both products do a fine job in scrubbing PO4 from the system.
Better than other brands used By Mike on 8/7/2011

I have used a couple other brands of GFO in the past. after a day or two, they tend to clump up. I have had no clumping with BRS GFO. Thanks for offering a superior product at a great value.
Just what I needed to get the job done! By Robert on 8/3/2011

There’s no comparison, GFO took out more phosphates in a 24 hour time frame than its aluminum oxide competitor.

Great stuff at a good price. This GFO has low dust and tumbles quite nicely, all you have to do is tune your reactor till the output water is reading 0 P04 and your done.

Been using BRS HC GFO for the last 6 mos, and while it hasn't been able to take my levels to 0, it seems to be effective in getting them very low.

A great value By David on 6/28/2011
David would recommend this product to a friend
I started using this GFO a couple of weeks ago in my Phosban reactor, and it is helping greatly in my battle with nuisance algae. It is much cheaper than the other brands and just as effective.

I run BRS GFO for the last year and a half in my 250 gallon system and its great, it doesn't leach phosphates as some of the other product out on the market. It also work very well in a media reactor as it doesn't break down.
GFO AWSOME By Melvin on 6/9/2011
Melvin would recommend this product to a friend
Every product that I bought so far works way beyound my expectations and the GFO is no exception. It is perfect for the reactor. Its like a magnet for Phosphates. ZERO in just 18 hrs. BRS is awsome at saving you money in the long run. I wish I found BRS a lot sooner. I would have saved so much money doing things one time instead of many.

This matches the effectiveness of the name brands and comes a good deal cheaper. I can't justify going back to the others anymore.

I have always used this in BRS reactors which make it easy to use and replace. I watch the rate at which algae grows on my glass as a basis for when to replace my GFO. This product is great for beginners and experts.
