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!

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 3/17/2011

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 3/15/2011

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!

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 3/13/2011

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 3/6/2011

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
Great! By Hi Salenity on 3/6/2011

Man if you don't use GFO you need to! This is nice stuff with very low dust

I use GFO in BRS reactor along with snails crabs, shrimp and a tang to keep algae away. The only thing that grows on my live rocks are coral and purple coraline, thank you GFO!

for anyone that doesnt know, this product is basically the same as phosban. the only difference is the granule size may be a little smaller and that its a ton cheaper.
