I was looking for something to help with my saltwater algae problem and decided to try this and I have been extremely happy so far. I will say that I will be trying the higher capacity next because the space needed in a reactor is is greater in the standard GFO.

Great stuff! By Colin on 11/25/12

I got this GFO for my BRS reactor due to a hair algae problem I was having. After adding this and a lawnmower blenny within a week all my hair algae was gone! Works great!

Perfect GFO. I use this product in conjunction with skimming, carbon dosing (pellets and sometimes biofuel) and carbon with great results. My parameters stay in range, and the recommended starter amounts seem to work well for most applications.

Can't live without it By Casey on 10/30/12

I can honestly say gfo has made my life easier. Without it, I'd probably have to do 2 water changes a week with my desire to feed as often as I do. I'd never have a tank without gfo in a reactor.

Great value By Steve on 10/21/12

Nice value for GFO. Not as nice as the uniform spherical GFO you get with other premium brands, thus may not fluidize quite as easily, but gets the job done.

I was still having an issue with phosphates running Phosban, upgraded to the GFO reactor and haven't detected phosphates in my weekly tests again!

What can I say? Same product I'm paying premium price for in my local fish store at a much lower price. I didn't even notice the switch when it comes to water quality. Should have bought this earlier.

phosphates are 0 By Ray on 9/27/12

This is every bit as good as any other product on the market. I had been using phosban for years and decided to try this 6 months ago. well after 6 months phosphates are testing 0. What makes this more appealing is the price and quantity you get. There is nothing else like this in the market!

Ordered this when I originally set up my reef tank but didn't use it until about a year later. Changed my reefing life! Phosphates are way down and corals look great now

Works Great! By Toby on 9/21/12

Bought the granular (the cheaper of the 2) GFO's that BRS offers. I ran it in a Nextreef MR1 reactor and used the recommended amount from the BRS Reef calculator for GFO. It lasted 4 weeks (with heavy fish/coral bio-load). Phosphates dropped from 2.0 to 0.0 overnight. It stayed for about 3-4 weeks and began to creep back up so I removed it and increased the amount. Hoping to get 6 weeks out of it. I recently purchased the high capacity because I think it'll be a better fit for my system.
