Why does BRS recommend this?
All of the BRS reactors come with easy to use push connect tubing, flow control, and a refillable cartridge. We took easy to find components to keep things cheap, while designing an efficient easy to refill reactor for aquarium use. We keep hearing our reactors are the easiest to refill even when compared to others three times the price. When changing the media is easy you are more likely to do it in a timely fashion as well. We also recommend having an extra refillable cartridge on hand to make changing media that much easier.
Easy to use, setup and maintain. Perfect for utilizing GFO and Carbon in the aquarium. No annoying thumb screws and leaky lids like other reactors. BRS recommends a Cobalt Aquatics MJ 1200 pump to operate this reactor. Sold separately or packaged with the pump. Choose a different pump depending on mounting height and amount of media used.
The BRS GFO & Carbon Reactor features several distinct advantages over other brands.
- Ultra-transparent media cartridge allows for clear viewing of reactor media
- Heavy duty plastic construction

- Instantly attaches to popular pumps like Maxi-Jets using included push connect fittings
- 1/2" fittings and ports throughout reduce head pressure and provide ample flow rates
- Holds three cups of carbon (Approx. 300g) or two cups of GFO (Approx 290g)
- Dimensions: 14"H x 8.5"W x 5.5"
- Pump (optional) and media sold separately
BRS GFO & CARBON REACTOR - SINGLE By Cool Fish on 12/26/2017Cool Fish would recommend this product to a friendHave been using this for a few months now and like it so much more than the 2 Little Fish version. I always had trouble getting the top off that model. But, not so with this one. It's much easier to clean and is built more sturdy. I would recommend this product.
Clogs too easy By MrEwrasse on 11/1/2017MrEwrasse wouldn't recommend this product to a friendI've been using this for a few months now and find that it clogs too easy. I've used Rox and a couple other types of carbon and even with the sponge in, the carbon stays at the top of the chamber. After a few days the flow slows to a trickle... using a 400gph pump
Great reactor By collinsclan on 9/15/2017collinsclan would recommend this product to a friendMy wife bought the double a few years ago from BRS and it works perfect so I thought I would buy the single and use it as a media tumbler in my 60 gallon nano. It also works perfectly.
Bracket flimsy By Scrid on 9/10/2017Scrid would recommend this product to a friendThe mounting bracket is super flimsy. Added this along side my BRS Dual Carbon and GFO as a Bio reactor. The single Reactor bracket is not as deep dimension as the Dual reactor bracket.
So even side by side the canisters do not line up.
I may opt for a metal bracket on this unit in the future.
Great product By Frank on 9/10/2017Frank would recommend this product to a friendEasy to assemble. Works well with carbon or gfo. Can control the flow with valve.
Very Good Product By OneCoolFish on 8/11/2017OneCoolFish would recommend this product to a friendALways had difficulty changing the contents of the "2 Little....." brand. Not so with this one! Cleaning and changing granules is much easier!
It works fine By Larry on 3/2/2017Larry would recommend this product to a friendI haven't had any trouble with it, running carbon and gfo in it since Christmas. My sister in law got me the hook up on this. You so have to make 100 percent sure the carbon and gfo are mixed well, buy that's not the reactor. Imo the system works great.
Clogs By Mike on 1/27/2017Mike wouldn't recommend this product to a friendIts a good concept, but it does clog pretty quickly. For the first week or so you have to monitor the water flow and clean if necessary.
Carbon Reactor By Michael on 1/8/2017Michael wouldn't recommend this product to a friendI needed to mod Reactor it clogs pretty quickly. need to cut the bottom slot plastic for more flow
A simple reactor By Bbdb on 10/30/2016Bbdb would recommend this product to a friendThis reactor includes just about everything you'll need hoses coupling, valve, and of course the reactor. everything included is of great quality, and I didn't think twice about buying from BRS.
Works a lot better than other name brand reactors By Tyler on 10/22/2016Tyler would recommend this product to a friendBeen up and running for two weeks now and I am impressed. Had other "popular" reactors that began to leak after 1 year. Only advice is to ensure you cut the tubing straight and ensure it is pushed all the way in. I also had a leak from the elbows as well after the initial install which was alleviated after I cut the tubing straight and pushed the tubing in as far as it would go!

The pump does not come with them in the box but they are available (and suggested). I have included a link below:
You would want to run it separately from a biopellet reactor. The two medias require different rates of flow and would have negative effects on each other :-)
You certainly can run it in a reactor without issue. Reactors are able to pass more water over the concentrated media and will inherently have better performance. Feel free to let us know if you have any further questions!
the main reason is flow for the tumble. when multiple media are used it certainly will take up room in the chamber, in most cases there is not enough room for a tumble when the canister is taken up with carbon. While this could work on smaller systems 30 gallons and under, larger tanks would need more media and inherently more room to tumble. Feel free to let us know if you have any further questions!
Not a huge problem unless you find the water is not flowing out of the reactor. This can be mixed up and adjusted flow to attempt to correct the flow in the bottom of the GFO. Feel free to let us know if you have any further questions.
this is due to media capacity and flow through the media. While you can change out media more often for best performance and cost efficiency a larger reactor is recommended or a dual to separate the GFO and Carbon. Feel free to let us know if you have any further questions!
(I note my intention is to add LEDs and use the unit as a Cheeto reactor).
Provided you choose a pump with sufficient flow you shouldn't have any problems mounting this unit as described. The canisters are rated to pressures far exceeding the capabilities of any aquarium pump.
My only concern would be water spillage when opening the canister. I would recommend installing 2 valves as close to the reactor as possible while leaving some space between the elbows to allow you to remove them if need be. Placing a tray or other container under the unit would help reduce the impact or any spills.
Hope this helps!
The max capacity for the reactor would be a total of 3 cups of media if it doesn't need to tumble (like carbon/gfo mix). If you were actually maxing out the reactor though you might want to consider a larger pump then the standard mj1200.
All of our reactors use 1/2" tubing and fittings, hopefully you have some of that laying around too!
You will want one rector for Carbon and one for GFO on a 150 gallon tank. Feel free to let us know if you have any further questions!
The reactor is a great way to tumble GFO or run carbon (or both together) to keep colors and odors under control and Phosphate levels to a minimum (with GFO). This unit is designed to be used in a sump in most cases and not hang on back. Feel free to let us know if you have any further questions!
Also, do I place both the intake and output hoses of the reactor in the same sump chamber? Or should the outflow go directly into the last chamber with the main return pump?
No need to run carbon in a bag when your using a reactor. The idea isn't to run all of the water through the carbon in each pass (which largely isn't happening now either as you will get things like channeling with a bag). When it comes to which chambers of the sump, most people return to the same chamber as you don't have to worry about creating odd siphoning issues but largely its just a matter of convenience. Your cycling the water from the tank over and over again so its not a big deal :-)
It has a capacity of 2 cups of GFO or 3 cups of carbon. How big of a tank that works for really depends on what specific media you plan to run. What type of GFO or carbon were you planning to use in the reactor?
This will depend on what pump is used. With the Cobal MJ 1200 pump you can expect flow at maximum 200 Gallons per Hour. Feel free to let us know if you have any further questions!
Really just about any pump in the 300gph range will do the trick, the Cobalt MJ1200 just happens to be any easy fit. The only pump I would avoid is the marineland maxijet 1200, as they are quiet loud when used for this purpose.
Do you just sell the tops?
What adapters would I need to facilitate that connection? I know I will need a 1" PVC Y valve, but from there, I need something to knock down 1" PVC to a 1/2 flexible push connector. I can split that Y again for the 2 reactors. Help?
You will want to use a Reducing Bushing 1” Spigot x 1/2” Female Thread and a 1⁄2" Male NPT x 1⁄2" Push Connect to adapt your reactor plumbing to your return line.
I would avoid multiple Y fittings and make a manifold using a T off you main line running to another T for one reactor and then the end of the line going to your second reactor.
I know its difficult to describe so take a look at this to get an idea of what I am going for.
Each output will need a valve as will the line going to your tank. Getting the flow right to each reactor and your display tank can be a little tricky but you should only need to do it once.
Hope this helps!
Have a great day :)
They are just 1/2" push connect elbows. Its possible you may be able to find that at the local hardware store, though 1/2" is a bit larger then they usually come. If not they can be found right here:
It is 1/2" RO tubing. More can be found at the link below. Honestly it wouldn't really be worth it to try and adapt to a different type of tubing as you would basically have to rebuild the whole filter. I would suggest just using a push connect elbow if you need to go around a corner, that way you also won't have any issues with kinking.
If you are going to use them both in the same reactor but not mixed, you would use a sponge pad as a divider. That said though, if you aren't going to mix them you may be better off with a dual reactor which will make it much easier to change the media.
We certainly do, the replacement pads for our reactors can be found here: https://www.bulkreefsupply.com/brs-reactor-replacement-pads-hard-shell.html.
Its not a problem to mount the reactor behind the tank or something to that effect as well. It doesn't hang on back, but so long as you have somewhere to put it, its not problem at all to use it on a tank without a sump.
That shouldn't be a problem at all. The reactor should have enough room to hold the amount of media you need to run with just about any type of GFO or carbon you use on a tank that size.
Changing the media is actually really easy. You just want to make sure that the pump is off and then you unscrew the bottom canister. While you might spill a few drops if your careful almost all of the water will stay in the bottom canister and you can carry the canister media and water to the sink to drain it and replace the media. You can leave the main bracket mounted, the pump in the tank, etc.
The BRS reactor does not hang on the back. Units that hang on the back aren't as common, the phosban reactor is the model most folks will use in that situation. The same cobalt mj1200 is a great pump option for it as well.
The biopellet reactor doesn't have foam pads and it also includes fittings for a larger pump (bigger pump is needed for biopellets) wheras the gfo/carbon reactor only comes with an adapter for the cobalt pumps.
We sure do! You can find them right here:
