Was dealing with an algae problem that turned out to be caused by elevated phosphates. Guys recommended GFO and reactor so I watched the BRS videos and set to it! Made a very good investment-tank is algae free and I'm happier not looking thru slime covered glass. Gonna try the higher performance GFO next!

Battling stubborn hair algae for a long time and finally decided to try this out after reading all the good reviews here. I still have algae now but way less and it isn't growing and spreading everywhere like before. Just a little patch. This stuff keeps hair algae in check! It works.

I think the Bulk Reef Supply GFO is the best you can buy. I have used it for 3 years. Great product. Phosphates stay at zero!
Definitely a good buy.

A great media for reducing phosphates. Highly recommend using this product. Would suggest using in a reactor for best results.
Amazing Product By Edward on 2/4/2014

Ive tried a couple GFO's and I have to say this has been the best at keeping phosphates down. I ordered it with BRS carbon and the dual reactor. The best part was the price and knowing the reliability of BRS products.

I received this product in December and have been using it ever since. It has made a large impact on my phosphates and I would recommend it. It has lowered my phosphates to nearly zero.

i use this in a brs reactor and it works great
great overall By Nicholas on 1/15/2014

Product is good, however I will choose the high capacity next time, because there seemed to be a lot of fines with the regular gfo.

Phosphates stay right at 0 By Matt on 1/15/2014

I use the GFO in a fine mesh bag in my canister filter. It keeps my Phosphates right at 0 unless I feed heavily, then it pulls them right back down by the next day. The grains are very small, use a fine mesh bag if you need a bag.
This stuff is REEF MAGIC By Vince on 1/14/2014

Don't even bother with the cheap imitators, this stuff not only is cost effective but it takes a while to deplete. Be careful to dial in the right amount or you can have a huge drop in your P04 and can harm some corals, I noticed I couldn't get my p04 under ~.5 until I ran this in a reactor which I only recommend.

This is the first time I am using this. I usually buy the high capacity gfo, which is a great product., but it is sooooo expensive, I decided to try this. I haven't noticed any bad differences, so I am rating it great. But I am keeping my fingers crossed that I did not make a mistake.

Excellent standard GFO By George on 12/30/2013

I used this before I bought the high capacity GFO. Unless the high capacity is on sale, this is the way to go. Inexpensive and an excellent way to control algae!
Did it's job By Chris on 12/24/2013

Product brought my phosphates down however it is very fine and I had to reduce my flow rate dramatically in my reactor. I have since started using another product which is way more granular and I am able to increase the water flow to my reactor thus getting more water treated.
With BRS however you get way more product for your buck. So it's hard to beat

Ordered product to mix with carbon to remove phosphates it did so and overall water quality has improved
VERY dusty. By Quinnchero on 12/18/2013
Quinnchero wouldn't recommend this product to a friend
I realize I'm spending a little less on BRS products and shouldn't expect the world out of them. With that said, the GFO arrives very worse for wear, seems like the packing guy shook the container on a paint mixer for an hour or two! easily 1/3 of the pound was entirely useless; making the purchase actually WAY over priced for usable product. Sorry BRS, I LOVE your store and most of your own branded product, but this one has failed me a few times now.

I bought a gallon of this. It's does what it says... I change it out every 3 weeks and my phosphates stay at 0.

works ok. i run it in 2 reactors for my 300. feed responsibly and I still have some phosphate. A little on the pricey side IMO for how it performs

This product is excellent and does what it's meant to do! See my other review on the GFO reactor.
