I could see the growth take off on my sps corals immediately after using this. Highly recommend.
Cuts down that Phosphate By Jetthril on 3/30/11

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 3/20/11

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!
Best GFO on the market By Rick on 3/17/11

Don't be fooled by other "branded" GFO, this one works, and works well. I've used it for years and test 0.0 PO4!
Effective GFO By Michael on 3/17/11

I have a 100 gallon heavily stocked SPS tank. The BRS Granular GFO is by far the best cost saving choice and maintains phosphate at nearly zero as well as any of the name brand GFO. I've tried many of the different types on the market and have observed no difference in coral growth and calcification. It is an effective GFO at a fraction of the cost. Keep in mind that running GFO is reported to knock down magnesium levels. You may need to order the magnesium supplements from BRS and a test kit to maintain your levels. Another option is to run GFO sporadically to knock down the phosphate levels and reduce amount you feed. For best results start running GFO with a new tank.
What Phosphate? By Kevin on 3/15/11

What can I say about the GFO? it works as described and extremely fast. The cost is super cheap compared to other brands and way more then enough to last for months. Great job BRS!

I order this stuff after I got an algae break out and this stuff cleared it up right away. 5 stars all the way!
Does what it is supposed to do at a fair price By Larry on 3/14/11

I run BRS GFO in a 2LF 150 reactor. Keeps phosphate levels @ 0. Did a great job helping me get rid of some hair algae.
Great product and better price!! By Ryan on 3/13/11

This GFO is great and is working wonders on my reef tank and has ruduced my phosphates to nearly zero and twice as cheap then my local pet store and is one of the most important things to use in a reefer tank IMO..
amazing product By Jason on 3/7/11

I use this in a gfo/carbon reactor and the water clarity in my tank has a drastic improvement. I no longer have to clean the glass every day, its now once a week
