works like all the other anti phosphate products at what seems like a quarter of the price.

I did my homework when it came to adding chemical media in my reef. I have no complaints with this GFO. My Phosphates levels are always nearly undetectable and no algea, just make sure you rinse well before use.
Performs well - But needs to be rinsed Very Well By Alex on 7/19/2014

We used the High Capacity GFO first and it worked great. This time we decided that since we had a large reactor and plenty of space, we could use the GFO that wasn't as compacted to be a little cheaper . It worked for its primary purpose - get the phosphate out. It's just that we had to rinse it with several gallons (5-10) of water to get the dust out and it still left orange dust on the bottom of my sump. I think we will go back to the high capacity stuff after we go through this batch.

Was experiencing Phosphate levels of .10 ppm set this up with the BRS dual reactor. After 24 hrs PO4 dropped to .05 ppm and after 48 hrs PO4 dropped to .01 ppm. Thanks BRS!

I had problems with phosphates and every product i used temporary lowered my levels for only a few days, and even then only had them down to 0.04. I decided to order this product along with the BRS reactor and i am not disappointed. I had this stuff in for about 1 week and on the 2nd day, i had 0 and i mean 0 phosphates!

I have used this GFO for a few months now and have had no issues other than the typical dust that comes with all gfo products. I just run 2 gallons of ro water through it and have no complaints!
Great product that does what it says By Eric on 5/7/2014

This stuff is great and absolutely reduced my phosphates. I've also used the high capacity. The bulk gfo does clump quite a bit and produces dust. I buy the high capacity now with no problems. Great stuff though.
Good Value...but needs frequent changing By Daniel on 5/3/2014
Daniel would recommend this product to a friend
This media is a great value, the cost is well worth it for the performance it provides. The only reason I didn't give it a five was for the fact that it solidifies faster than the BRS High Capacity GFO when dosing 2-part.

I have no idea why I have not started to run this in my aquarium my corals started to open better after I started to run this in the BRS Dual Reactor. This stuff works great and it last a long time as well. Also I started to see some algae growth and after a week it started to disappear.

I've used pretty much all the major brands over the past several years, and I've got to say this is the best GFO in the industry. Thanks BRS for making a great product, and making it affordable to have a clear tank, also your small particle lignite carbon and is a great product as well.

Looking for a less expensive alternative to lower your phosphates. You found it. The BRS GFO is a great value for the money, especially for large bulk purchases
