Even with just running in a filter sock, my phosphates dropped by half in just 2 weeks. MAKE SURE YOU RINSE BEFORE USING. This stuff turned my tank red for about 2 days, but that was my own fault. Highly reccomended!

Great product, I would highly recommend to everyone. I use it regularly in the dual reactor and have had great results.

This product exceeded my expectations from what I had in mind after seeing the price. This is by far some of the most effective media I have found to date. Within 72 hours, my PO4 levels zeroed out and have not risen in two weeks. Amazing stuff!

Purchased this a couple of years ago when it was sold in bag form and it's a solid performer. Performs just like the big brands at a fraction of the price.
Great product! I will be buying more of this! By Chris on 5/9/2011

I bought this due to it's phenominally low price, and was a little hesitant. It turned out to be an excellent product, and easily performs as well as the higher priced brand name types. I plan to buy more, as soon as I need it. It doesn't require a ton of rinsing, and if you use half the recommended dosage, but change it out twice as often, I've found it works better at reducing algae, and keeps the system more stable. Thanks, BRS!

An absolute must for a reef tank. Does an excellent job removing phoshate from the aquarium.

Don't have a big problem with phosphates but I still run this product 24/7. Easy to use.

I could see the growth take off on my sps corals immediately after using this. Highly recommend.
Cuts down that Phosphate By Jetthril on 3/30/2011

Unlike most other folks would use this product in a reactor, I used this product in a media bag. Be sure to rinse out the dust before use. Due to the fact that the GFO bunches up after getting wet, I would recommend using less than what the calculator on this website recommends and change the media more frequently (not every 8 weeks), that way you water can more easily flow through the media, and the GFO can more easily take out the phosphate in the water.

Works great in a Freshwater Planted Tank By Duane on 3/20/2011

I first of all borrowed some GFO from a fellow reefer to use in my Planted FW Discus 90gal. I was having a terrible time with algae. I followed the directions on the BRS "Information" page and set up a reactor with the GFO. Within a few days, my Phosphate level went for a 2ppm to a .5ppm. The GFO helps maintain the Phosphates at a acceptable level. It does not zero the phosphates out because my substrate leaches phosphates into the water and I want low level phosphates to aid in plant growth. So I have found this stuff works perfectly for me. So I purchased my own BRS GFO, which is a much better buy than the name brand. Thanks BRS!
