Does what it should. My only complaint is the particle size, as it can work through the sponges in your reactor. Makes setting the flow a bit tricky. I would suggest starting with a little less than the recommended amount by the BRS calculator. GFO can and does release Iron into your system, so use only what you need. Saves your system from Iron (HARD to get back out) and your wallet, at the same time! Also, I run one gallon of tank water through my reactor, to rinse, when I change it out. Helps a lot with the fines.

I run this GFO in a mesh bag in my sump (no reactor), and it has helped with PO4 in my FOWLR. Very reasonable price, too.

this was a great addition to my tank. cleared up my algae problem within the first few days of use. the BRS calculator was a big help with this as well.

GFO works great as part of my filtration system to keep everything in check. I just added a reactor to the mix to make better use of my media.

This is a must if you want to have a successful reef tank.

This stuff works great and I save money. What's not to love? No complaints. My wife commented my SPS corals looked happier and more colorful just a few hours after I started the GFO reactor.

be careful of how much flow you use to make this tumble.if you run too much it blow some it into your sump area.other than that works to keep phospahtes low
Good product. By Felixpaws on 3/13/2013

I've used this for years, and I highly recommend it, for its phosphate reduction. I have no choice, but to use unfiltered well water, and this works great to reduce phosphates, in my 75 gallon, and 120 gallon reef tanks. I have a clam, anemones, and sps in the tank, all growing great.

notice less algae on the glass. the particles are fine and i gave it a little to much juice the first time and gfo was all over my sump and display.. so low flow through the reactor!!

I was having problems with GHA, though my Nitrates and Phosphates tested in the '0' range. Upon addition of GFO, I noticed a reduction in the algae. It would no longer return when I physically removed it. It didn't happen overnight, but the reduction was obvious. I put about 4 OZ in a bag in the sump and replace every several months. It's part of my routine maintenance.
