    Would running one of these types of reactors be overkill on a Biocube29? Im wanting to run both GFO and Carbon and dont think the innovative marine will do so. Would also like something that I can use when i upgrade to a 90 this spring.

    Bulk Reef Supply Hey Chris,
    Thats not an issue. The chambers may look a little empty with the amount of media you use for a tank that size but it won't hurt anything and youll have it for your big tank this spring.

    What's the best way to connect a pump to the reactor? I have an extra Maxi jet 1200 I thought I'd use, but the outlet is exactly the same size as the tubing for the reactor and the ½" reactor tubing won't stretch to fit over it.

    Bulk Reef Supply Hey Patrick,
    All it takes is a 1/2" push connect union which the reactors themselves come with. Otherwise I have them linked below as well.

    Considering a brs carbon and gfo dual reactor. What is the gfo component and what does it do. Thanks brs team you guys rock

    Bulk Reef Supply Hey John,
    GFO stands for Granular Ferric Oxide and it is a phosphate remover. Its actually one of the few effective ways of removing phosphate from the tank which is pretty important as its not only an algae food, but it also inhibits the growth of stony corals as well. Here is a short video we did on GFO

    Hello,
    I will be upgrading my tiny 14 gallon tank to a nice 50 gallon soon. Is this product recommended for a brand new tank?

    Bulk Reef Supply Hi Hank,
    I would suggest running GFO and carbon on any tank, even better if its a new tank as you can help keep it in good shape rather then trying to to recover after things get out of hand.

    Looking to buy a couple of the ball valves included with this reactor. I don't see them listed separately on the site.

    Bulk Reef Supply Hi Lance,
    They are 1/2" inline ball valves. They can be found right here:

  • by Travis on January 31, 2014, @5:47 AM

    I am looking to buy the Dual GFO/Carbon reactor. How often should I replace the GFO in the reactor? and does it release phosphates back into the water once it has reached it usefulness?

    Bulk Reef Supply Hi Travis,
    It should be changed once its capacity has been reached. The best way to know this is to monitor your phosphates with an easy to read phosphate meter like a Hanna phosphate checker. Usually this is about 4-6 weeks but entirely depends on how much phosphates you have, which is almost entirely related to how much you feed. GFO will not release phosphates back into the aquarium however once its reached its capacity it will no longer be removing new phosphate so the levels will begin to rise.

  • BRS Dual Reactor By Gus on 5/1/2015

    I had to make sure the water lines ere firmly seated to avoid leaks. I also need to adjust the amount of Carbon and GFO to get better results. so far the unit is giving acceptable results. I expect better numbers as I tweak the amount of media.
  • Easy to install By Chase on 4/27/2015

    This item is idiot-proof, which is important to me especially. The quick connects make this a breeze to install.
  • Fool Proof By Chris on 4/22/2015

    As a beginner hobbyist with only about six months of experience, the dual reactor really makes it seem so easy. you can see your media working and the plumbing involved is literally fool proof. Just what I needed. For small stands like mine, its a little bulky but other than that no bad words can be said.
  • Simple install By James on 4/15/2015

    My water is noticeably cleaner. What a great price and the install instructions are simple and clear. I wouldn't hesitate to buy this again.
  • thanks5 By toots on 4/14/2015

    We love it tank is clean everything in our tank is doing great I would tell all of our friends about this product
  • I would do it again By Jerry on 4/9/2015

    I'm no plumber. The video's here and instructions that came with it made it understandable and as simple as possible. Big difference over night with clarity and lowering phosphate with GFO in one tube and GFO and carbon mixed in the second tube. 200 gallon tank with heavy bio load so it will tank a while to get to where I want but at least I'm now heading that way. No leaks or problems.
  • Love it! By Kendall on 4/9/2015

    I bought two of these for my freshwater tanks so I can run carbon and phosphate remover. I was originally going to make my own out of separate purchased components, but the cost of the BRS system changed my mine. I was able get all the components from one source and I knew it was going to work when I received it. Would recommend to anyone looking for an easy to install and use reactor.
  • Gets the job done By Mike on 3/29/2015

    I have this set up on my 120 gallon reef tank and it gets the job done having dedicated GFO and carbon. keeps my water clean and my phosphates down as well as very easy to maintain all set with the price can't be beat
  • Awesome By txaggies07 on 3/27/2015

    Works great. This is far better than the previous system I had. The system is well made and easy to get up and running.
  • gfo& carbon reactor By Izzy on 3/25/2015

    excellent product and easy to hook up with instruction and videos if you don't know how to use it,I would definitely recommend to all my friends.
  • Single dual reactor By Greg on 3/24/2015

    I'm splitting the dual reactor to create 2 single reactors with a "T" and another ball valve run off of one pump.
  • Very nice product, wish it was bigger to place more media By Harold on 3/17/2015

    A great product, just opened the box and 20 minutes latter it was running with no leaks or problems. Just wish it was bigger to place more media…
