- BRS GFO & Carbon Reactor - Deluxe
Why does BRS recommend this?
The Deluxe reactor has a slimmer form as the bracket is molded directly into the canister head, as well as integrated push connect fittings to keep things as compact as possible. Along with the standard 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.
Deluxe BRS GFO & Carbon Reactor comes with the following features over our standard BRS reactor.
- Sleek black styling
- Heavy duty built In bracket
- Included elbows for easy hose routing
- Pressure release for allowing air to escape
- Lower profile canister with increased transparency.
Ultra-transparent media cartridge allows for clearest viewing of reactor media
The Deluxe BRS GFO & Carbon Reactor is designed to be easy to use, setup and maintain the BRS fluidized reactor is perfect for utilizing GFO and Carbon in the aquarium. several distinct advantages over other brands.
- Ultra-transparent media cartridge allows for clear viewing of reactor media
- Heavy duty plastic construction
- ½" fittings and ports throughout to reduce head pressure and provide ample flow rates
- Swivel 90° fittings on both sides of the unit for easy positioning of the tube

BRS GFO & Carbon Reactors use 1/2" Push Connect fittings and 1/2" Mur-Lok Polyethylene Tubing
Brs reactor By Victor on 12/8/2018Victor would recommend this product to a friendI love it. Be it doesn’t come with the correct fittings to connect to the pump that it comes with. I hate having to go and try and find parts at the depot.
Works great By Drewski on 10/2/2018Drewski would recommend this product to a friendHave 2, one for gfo and the other using for bio pellets.. working out great.
Necessary & affordable. By BigBossReefer on 8/10/2018BigBossReefer would recommend this product to a friendI can’t believe that I waited so long to buy this. It’s easily one of the most important (& affordable) filtering devices in my aquarium. I use it for GFO ran most of the time and rox carbon+phosguard every 2 months for one week. It is so much more efficient than throwing a bag of media in a filter sock. There is a lot value for the cost!
Excellent Product By Ken on 4/28/2018Ken would recommend this product to a friendWOW, why did I wait so long to add this? Reactor is built like a tank and the MJ1200 is whisper quiet. BRS has made an excellent product that is quick and easy to install...thank you Mur-loks! I placed the Reactor output tube in my sump DOS chamber so I get an added benefit to stir the water constantly while dosing....Oh, and my water is crystal clear!
Does the job! By Josh on 4/17/2018Josh would recommend this product to a friendWorks great. Have had it running with a Maxijet 1200 with no issues.
Great reactor By Mattx on 3/28/2018Mattx would recommend this product to a friendBought this reactor over the basic reactor BRS makes because of the reviews for mounting and I know I made the right choice. Heavy duty plastic mounting bracket is nice. I have carbon running in it so no thoughts for GFO but works great otherwise. Didn’t get it with the pump as I had an extra Sicce laying around. Would buy another one if for some reason it broke.
Awesome product By SC Reefer on 1/29/2018SC Reefer would recommend this product to a friendhttps://www.youtube.com/watch?v=ZXzDPETpd7M
Straight By Lucas on 1/15/2018Lucas would recommend this product to a friendCan't compare it to other reactors because this is the only one I own. But the canister itself is awesome. Pump died 5 months in. I didn't clean it or anything though. Push connects can be a little drippy if you don't maintain. Solid product i would buy it again with out the pump though.
Does what is says but puts fines into your tank By Trent on 1/14/2018Trent would recommend this product to a friendI set this up to tumble GFO. Even on what seems to be the lowest setting to keep the GFO slightly tumbling and the sponge in place to keep the fines from escaping into my tank the water is brown and cloudy. I put the outlet into my sock filter and it cleared up significantly. It does mean I need to switch out my filter sock every 1.5 to 2 days which is problematic. I'm going to try the high capacity GFO when I exhaust the regular BRS GFO that I ordered with it. All that being said my phosphate dropped to a lower level than I can detect with my test. If the higher capacity GFO doesn't work I'm thinking about setting up a filter sock just for the reactor outlet.
Great product By scott on 12/10/2017scott would recommend this product to a friendReceived this reactor a few weeks ago and I am very pleased with the ease of set up and use. I am currently using it for carbon only and it certainly beats using bags of carbon.
Great! By John on 11/28/2017John would recommend this product to a friendGreat quality product. Heavy duty, will never have to replace. Easy to install, no leaks. The MF1200 pump is a little chintzy, but it works.
Reactor By William on 11/17/2017William would recommend this product to a friendThis product does what is says and worked well for me with no leaks. Also easy to install.
Im looking to upgrade my dual reactors version for my 180g mixed reef due to more bioload now, will this deluxe size here work for running GFO (regular media) and Carbon (Rox type) separately? According to the reef calculation chart or should I go with the Jumbo version? Also is the fitting hose the same size as the dual version hose? Thanks
You would want the jumbo as the deluxe would not be large enough for running the GFO as it would require more then the 2 cup capacity of the reactor for GFO. ROX carbon would be fine in the deluxe though though. The hose on all of the BRS reactors is the same 1/2" hose.
Can this reactor be hooked up to another one> in order to run GFO and carbon separately while using the same pump?
It can be physically but generally isn't recommended as in practice it requires a lot larger pump if connected in series, and if connected in parallel can be a bit of a pain to keep the reactors in tune.
How does the MJ 1200 connect to the reactor. The tubing included does not fit.
There is a small 1/2" push connect union that connects the two, it is white and looks a lot like the grey ball valve but without the valve (though you could actually use the ball valve itself if you wanted as well).
Where can I find replacement O rings for this reactor?
This one right here would do the trick:
I see in the description that you recommend having extra refillable cartridges for the media reactors, and while I agree that this is an excellent idea, I am having trouble locating them. I found the ones for the mini reactor but not the full size. Do you sell extra cartridges?
I have included a link below. Feel free to let us know if you have any further questions!
I'm buying the deluxe pkg with the MJ1200. 1 for gfo and 1 for rox Carbon. Will the flow be the same or is there a way to adjust it since both media require different flows.
The Flow will be different for Carbon and GFO. Ideally GFO will be tumbling and can be tuned using the included ball valve. In addition Carbon should not tumble and run smoothly with sponges on top and bottom in most cases.
Can I put a bag of chemipure and/or its elite/blue varieties in the reactor to ensure flow through it? I assume taking it out of the nylon bag, it may be too fne and escape the reactor?
Also could I just stand the reactor outside the sump or mount it on the inside of the stand? Not enough room in sump to place it inside. Right now I have a TLF 150 reactor hanging on the outside. It seems to get clogged with a chemipure blue 5.5 oz bag in it.
Can you use bio medias such as Dr. Tim's Bio Pellets or NPX Bio Pellets or any other brands, or just GFO and Carbon medias. I'm looking for something that will be universal, not just one type of scenario. And why the larger mag drive pump, isn't the media supposed to tumble slowly for a even flow.
It wouldnt be a big issue to use the deluxe reactor with something like biopellets so long as you remove the sponges and it will generally require a larger pump, though its capacity for biopellets is about a cup so its only suitable for small tanks. Biopellets usually require a pretty good flow rate otherwise they clump together and don't tumble at all, hence the larger pump.
The red air release button on top of my unit came off (broke off?) while I was changing media and it seems to be missing a part. I have the button and a small spring, but it looks like there may have been a hex head screw inside the button? Can I get a replacement?.
We unfortunately do not have replacement pressure release components or canisters for the deluxe models. Feel free to let us know if you have any further questions!
Does the deluxe come with upgraded connectors and silicone tubing or do you have to purchase that separate? Thanks
The deluxe will ship with standard polyethylene tubing. It will come with the same high quality mur-lok connectors however. If you would like to switch to silicon tubing we do have a separate kit available.
My canister top inlet elbow is broken. Do you sell the parts so that I can replace it? If not, wonder where I can buy one instead of replace the entire unit?
We have replacement elbows available which are stem x push for replacement of the Deluxe elbow. I have included the link below!
Black Elbow - 1⁄2" Stem x 1⁄2" Push Connect
I purchased one of your deluxe units today to run carbon only on a 65 gallon tank. In combination with a skimmer will phosphates be an issue or is a GFO reactor the only means? I have fish only now and will do corals after established for a year.
For phosphate control we find GFO to be one of the best supplements and easily can be incorporated into your reactor you already have! You can mix GFO and Carbon together in the reactor (making sure the GFO is not touching which may cause clogging) Feel free to let us know if you have any further questions!
I'm completely new to this and setting up my first tank. So far I am starting out with a 75g and incorporating a herbie style overflow to feed my 20g long sump/refugium that has an eshopps s120 skimmer. Instead of running socks, can I run this and plumb it in to the hardline with no pump needed? I was thinking of running both carbon and gfo in the deluxe together, will this be sufficient for a 75g?
Overall you will need filter sock to remove larger particles from the tank! The reactor is used for carbon and GFO filtration to remove odors, colors and with GFO phosphate from the water. Running both GFO and carbon in the deluxe will work with the 75 gallon just fine! Feel free to let us know if you have any further questions!
When using gfo in the reactor do u need to use the road sponge pads?
It is not required when running GFO as its ok (and usually encouraged) for the GFO to tumble. It is also coarse enough that it largely won't fall through the bottom of the cartridge (not that it hurts anything if it does either).
Will this reactor work well with this pump?
Compact Pump 1000 (267 GPH) - Eheim
Have a great day!
What size filter pads does this unit need?
Are they 3 inch round with a center hole or 4 inch with an offset hole?
These don't use any sort of standard size sponge, it uses sponges specifically made for the reactor cartridges which can be found right here:
I have a 300 gallons what kind reactor do I need for GFO and carbon to run my 300.?
If you use regular Bituminous Carbon you will need a reactor which can hold over 3 cups of Media. This can Include our BRS Jumbo Reactor which holds up to 6 cups. As for GFO if you select standard GFO you will need 4-5 cups total of media. Feel free to let us know if you have any further questions!
Im looking at installing an inline reactor for just GFO (one less pump in my 60 cube becuase of space/heat/efficiency). I was wondering if this reactor would work. To handle the adjustable flow to tumble the GFO i thought about getting an adjustable DC return pump. I also want to future proof my equipmemt for a 125 Gallon tank I plan to get in a year.
How could one put this reactor inline?
This reactor can work great in a manifold running off of a larger pump. You can simply purchase the kit and use the Mur Lok adapter listed below to connect the Polyethylene tubing in the kit to standard PVC threaded fittings in a 1/2" size. Feel free to let us know if you have any further questions!
1⁄2" Male NPT x 1⁄2" Push Connect
What is the recommended GPH to be passed threw the reactor when using carbon and gfo combined. It will be on a AIO so the reactor will be mounted in the cabinet below and I would like to purchase the right pump for the job. Thanks
1⁄2" Male NPT x 1⁄2" Push Connect
Could this reactor chamber successfully be used as a second chamber for a calcium reactor?
You could use the rector body as a secondary chamber for a calcium reactor, or even a nitrate reactor. You may need to adapt some fittings to get the ½” push connect fittings to plumb up to your calcium reactor, but you definitely can use it. : )
How do you recommend rinsing the media if you buy the additional cartridge without removing the reactor?
I personally like to always keep an extra cartridge on hand. You simply just fill up the extra one with your media, then turn the reactor off, and take out the old cartridge and place the new (unrinsed) cartridge and media into the reactor. Once you get it sealed back up you will just want to grab the output tube from the reactor and collect the first gallon of water or until it runs clear. I find it best to do it right before or after water changes when I have extra saltwater mixed up.
will this reactor work with purigen?
Would I be able to mix carbon/gfo in this unit for 120g tank?
This will only work if you use High Capacity GFO and ROX carbon. At this point we instead recommend 2 reactors or a dual to enough coverage and room to tumble. Feel free to let us know if you have any further questions!
Would like to know if the BRS deluxe gfo/carbon reactor is available in a dual model or if a singal 10inc canister is offered to add on to make a dual? I have a waveline 10k I'm using for my return and to run the gfo carbon reactors.
The deluxe reactors have brackets molded into the heads of the canisters which disables us from connecting two deluxe canisters directly together to create a dual reactor, but if you wanted to mount each one individually side by side you could make a dual reactor with a small piece of tubing connecting them. We do not sell the deluxe canisters separately at this time, but it wouldn’t shock me if you see them for sale individually in the near future.
Do you sell the O-Rings for this reactor? Mine are wearing out and stretching and I'd like to have a backup... Thanks!
We sure do! These would be what you are looking for:
Why does my reactor keep filling with air? Extremely loud and I can't seem to get the air out?
The reactors will fill with air if bubbles are introduced to the pump which will not easily allow air our unless the pressure knob at the top releases it. Additionally air can enter the system if one or more of the connections is not tight which can draw in air as the water passes. Feel free to let us know via direct email or phones if the issue continues and we will be more than willing to help!
Can i TEE off the mj1200 pump and run 2 of these deluxe reactors And have 2 seperate valves before the reactors to adjust flow???? One used for gfo and one for carb :)
Can I use pelletized carbon in this reactor with GFO, or does the carbon need to be a different shape?
I refilled my reactor, let the pumprun to clear the fines and then reinstalled in my sump. Now it will not function. Pump is not obstructed yet I get no flow through reactor. The valve is wide open as well. Any thoughts?
The first thing I would check is to make sure the reactor cartridge isn't in crooked. Assuming thats the case make sure the pump is pumping water (not air locked or something). Assuming it is pumping water, disconnect the tubes to see where the flow stops at. There isn't much (or really anything) to go wrong with one, so its most likely something silly like a closed valve or misaligned part. If you don't find the problem let us know and we will help you figure it out.
Could I use this on a 125 gallon reef tank that I plan on having a heavy bio load?
With high Capacity GFO and ROX 0.8 Carbon this could work well.
Would Seachem Purigan efficiently work in this reactor? In loose forn.
With proper care that the sponges are placed in the reactor you certainly can run purigen. Feel free to let us know if you have any further questions!
What is the width of the reactor around the middle? I want to see if it will fit in my lifereef media chamber rack hich can fit 3" media chambers.
I just ordered my second delux BRS reactor, so I can use one for gfo and the other for carbon. How can I connect the two so they can run together like the double unit you guys sell? Thanks!
It would be as simple as connecting the output from one reactor to the input of the next reactor. This setup isn't as ideal with two independent reactors though as the extra tubing and fittings will add extra drag, so a larger pump may be necessary.
Hi I just setup a 265g with 75 gallon sump I already have the dual chamber deluxe gfo/carbon. Does not seem to be working as well as it was previously on a 110 tall with 55 gallon sump. What do you recommend for my new tank thanks.
Hi I just setup a 265g with 75 gallon sump I already have the dual chamber deluxe gfo/carbon. Does not seem to be working as well as it was previously on a 110 tall with 55 gallon sump. What do you recommend for my new tank thanks.
You can use individual reactors with high capacity GFO and ROX 0.8 carbon. If you feel the tumble of the GFO is not enough a larger reactor such as Phosban 500 or BRS jumbo certainly can be used!
I currently have a 29G Biocube with the biocube protein skimmer without an air intake line. would I be able to place this between pump and skimmer and push the air instead of pulling air through it? Thanks
Unfortunately we are a little confused as to the wording of the question. The GFO deluxe reactor does run off of a feed pump (typically the MJ1200) he reactor does not have any air pushing or pulling rather the pump which can only push water through the system. Let us know if you would like follow up or clarification by email or telephone!
What size is the tubing that it came with, I just moved my tank to a different stand and need to get longer tubing for my reactor
Do sell longer hoses for this unit?
Will this deluxe gfo&carbon reactor work for the red sea reefer 350 reef tank? Also you you recommend mixing the gfo and carbon in this reactor ? And if not why is it that the dual reactor does not show the brs recommend logo?
The dual reactor will work great for your system! You will want to run the GFO and Carbon separately in their respective canisters. Many of our BRS made products will not have the logo as the reviews will speak for themselves! Feel free to let us know if you have any further questions!
Can this reactor be installed below the tank in the stand with the pump and tubes running up to the tank? I have no sump and I do not want to install this reactor above my tank.
This can work however you will want a few extra elbows and an additional mur lok ball valve to halt the flow when changing the media. the elbows will help to hold the tubing over the side of the tank. Feel free to let us know if you have any further questions!
I have a 100 gallon salt water tank including sump. Would one of these do the job? Also, does the GFO come with the system? I assume I can buy replacement GFO but how? I am looking at your BRS GFO & Carbon Reactor – Deluxe with MJ1200 Pump.
This can work will with the use of ROX 0.8 Carbon and High Capacity GFO. The system will not come with included media and it can be purchased separately. Feel free to let us know if you have any further questions!
I was thinking about purchasing this for a 55gal tank which isnt running a sump so I would be running it under the cabinet back up to the tank (around 30" of lift) is this pump enough to handle that?
You would want to increase the pump to something like the Sicce 1.5 for added boost and head height. The Sicce with the Mur lok NPT adapter in 1/2" size will be perfect!
I have a 40 gallon reef tank and I want to run carbon and GFO in one reactor. When I did the calculations on the website for carbon and GFO. It recommended about 5 tbsp each. Should I get the mini BRS reactor, or would this reactor work with this small amount of carbon and GFO? How would you keep the media from tumbling around?
The Mini will be a great fit for a system of your size. To keep the media from tumbling you will use the provided sponge pads to hold the media tight. Feel free to let us know if you have any further questions.
What style of pads does this reactor use? i see that you sell the hard shell and the old style.
We are currently shipping reactors with the Hard shell inserts. You can find the replacement pads here:
I hope this helps!
Have a great day :)
Hello and good evening. This question isnt really about the reactor. However it does deal with the pipe that comes with it to hook up from the reactor to the pump and return line. Can you please tell me what size the pipe is, and if you guys sell it. Also if u do sell it, where can I locate it on your web site. I need like 5-6 feet of it.
Thank you for the time.
The reactor tubing is just 1/2" Polyethylene (RO) tubing. It can be found right here:
I feed half to one full cube every other day. I do a 25 gal WC every other week. I have a sump with Chaeto and a big skimmer. If using two deluxe reactors, one for HC GFO and the other for ROX 0.8, how long will it take until I see a serious reduction in hair algae? Should I change the WC schedule to about 15 gal every week? I want my tank to look as good as it did a couple of months ago when I had zero algae.
It will depend on the phosphate level in the system. The Algae will still need to be removed by hand and lights turned off to take it back. The GFO will reduce phosphate levels to keep it from growing further. Feel free to let us know if you have any further questions!
I have installed the GFO & Carbon Reactor Deluxe and found it very easy to install. i am using just GFO (BRS) to reduce an algae problem and am curious how to get the best results. initially i think i had too much GFO, a full 2 cups, not compacted, and saw very little 'fluttering' of GFO particles - perhaps it was too full. my second attempt was just less than 2 cups and i not have a visual separation of the GFO in the middle of the container, about 1-2 inches, where particles are flying about. do i just need a bit more GFO, and should the particles be fluttering about at the top of the internal canister?
When completely filling with GFO there can often be slight separation in the middle depending on how quickly the flow was introduced into the reactor. Often starting the reactor slower will lower the amount of push up to the to. We recommend staying as low as possible with GFO for the tank to keep tumbling the GFO correctly I have included a link to our reef calculator which determines the amount to use based on tank size.
I was looking for a reactor for my 210 gallon tank is know this one is a small one do u have one that would work good for this size tank
Is this reactor and tubing suitable for running water coming out of an ozone reactor ? that is, will it not be damaged ?
I'd like to use it with activated carbon to eliminate any ozone from the water
This is not Ozone resistant and would fail prematurely if used with excess amounts of ozone. Feel free to let us know if you have any further questions!
I need to replace my tubing on my BRS reactor. Do you sell the tubing? What type do I buy if you don't sell tubing?
Where can I get that type of tubing?
Its just 1/2" RO tubing and we do sell it right here:
What is the difference between the Single & the Deluxe?
The deluxe is a bit more heavy duty as the bracket of the reactor is one piece with the top of the canister rather then being screwed on. The deluxe also comes with some additional elbows for routing your tubing.
If you were going to run carbon and the high capacity gfo at the same time howmuch of each would you use? And how long would it last? I really dont have any issues right now but want to avoid any algea issues. With tank and sump I am running about 135 gallons. Thanks
On a 135g tank you would 1 cup of the high capacity GFO. For carbon it would depend on the type of carbon, but assuming lignite it would be 1.25 cups. If your thinking of a different type of carbon you can use the handy reef calculator to do the math for you. It can be found right here:
Will this reactor work with biopellets?
The reactor itself is compatible if you remove the foam sponges from the cartridge, though keep in mind that bio-pellets usually require a larger pump then the mj1200 and this reactor doesn't include fittings for connecting to a larger pump like a danner mag drive (though they can still be purchased separately).
I have a 100 gallon corral tank that seem to be doing well. However, i constantly have to deal with accumulation of green algae. My nitrate, calcium, salinity and phrospate all seem to be good. What is my best action.
Thank you in advance
Phosphate and nitrate can be a bit difficult to get a handle on because your test kit only measures the amount of it currently in the water sample your testing. If it is being consumed by the algae, its not present in the water and can give a false sense of security in low readings. The first thing I would suggest is running GFO to remove phosphates while removing the algae in the tank, along with other good maintenance, water changes, etc. As you remove the algae from the tank it won't be able to consume phosphates as there added, which should then be removed by the GFO and not available for the algae to grow.
Can you run both gfo and carbon at the same time?
The reactor has a limited capacity (about 2 cups) so it will only work on smaller tanks, but you can run both GFO and carbon at the same time.
Can this be hung on the aquarium? Like the the phosban reactor?
Great question. Unfortunately the BRS reactor does not hang on the tank. It must be mounted to a stand/wall, etc or set in the sump. If you need something that hangs on the back of the tank, the phosban reactor will usually be your best bet!
