Product Questions

Can I run both gfo and carbon together in this reactor? I have read that they can, but Carbon is supposed to be run between sponges with no tumbling while gfo requires some mild tumbling.
Question by: Brick Rigden on Jun 22, 2024, 9:05 PM
You can run both GFO and Carbon in this reactor. At the end of this article, there will be instructions on how to do so!

Can this reactor be used as a CO2 Scrubber?
Question by: Tim Rendulic on Nov 4, 2022, 3:25 PM
Thanks for the question! This can be used as a CO2 scrubber, but you'll need to do some modification to make the tubing work with the larger fittings on this compared to the standard scrubber we carry. Let us know if we can help with anything else!
Answer by: Kyle Thomas (BRS Staff) on Nov 9, 2022, 1:10 PM
If I pop off the spring clip holding the john guest fitting from the main body are the entry and exit holes threaded so that I could use threaded male cupler (not sure on the exact name of the plumbing fixture). I would like to hard plumb the reactor.
Question by: John on Jan 22, 2020, 7:33 PM
Hey there!

Yes, they are threaded NPT fittings on the body of the reactor.

Take care

will this reactor work with purigen?
Question by: anthony krucek on Aug 16, 2018, 10:16 AM
The reactor would work with purigen, if not you can always use a mesh media bag in a high flow area. Take care!
Answer by: Mark Schlough on Aug 16, 2018, 12:48 PM
Do sell longer hoses for this unit?
Question by: William on Jan 29, 2018, 11:15 PM
We do carry longer tubing for the reactors. They use 1/2" push connect tubing that we offer in white or black.
Answer by: Charlie on Jan 30, 2018, 4:41 AM
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 :)
Question by: Gino on May 30, 2017, 8:14 PM
While you certainly could plumb the reactors together with a tee, I'm afraid the MJ1200 would likely not be powerful enough to split the flow in this fashion. I would recommend upgrading to something like a Sicce Syncra 1.5 or 2.0 for this.

Happy reefing!
Answer by: Zack on Jun 7, 2017, 3:24 PM
Will this reactor work well with this pump?

Compact Pump 1000 (267 GPH) - Eheim
Question by: chris hoerenz on May 28, 2017, 10:21 AM
That pump would be perfect for that application. The Eheim pumps come highly recommended by the crew here at BRS.

Have a great day!
Answer by: Zack on Jun 5, 2017, 4:36 PM
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.
Question by: Brian Kachel on Jan 8, 2017, 9:27 PM
Great question! The diameter of the reactor canisters is right at 12". :-)
Answer by: Randy on Jan 10, 2017, 4:25 PM
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
Question by: Stephen on Dec 6, 2016, 11:27 AM
Great question! Although there isn't a numerical recommended flow rate, you do want a flow rate that will lightly tumble the GFO. Since you are needing to pump the water down and back up from the cabinet, I would have to recommend a more powerful pump. In which case, the Sicce 1.5 and the fitting in the links below will be what you need to utilize with that reactor. :-)

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
Question by: Luis on Nov 22, 2016, 6:05 AM
Great question! Our BRS Reactors hold up to 3 cups of media, in which case if you are using High Capacity GFO, you would need 1.6 cups. This reactor would work in that case. If you needed something with larger volume, I would recommend looking at the Reef Octopus media reactors. :-)

Answer by: Randy on Nov 22, 2016, 3:32 PM
Can I use pelletized carbon in this reactor with GFO, or does the carbon need to be a different shape?
Question by: Eric on Aug 13, 2016, 6:44 AM
Great question! You could use pellet carbon in these reactors, however there are much better and more effective carbons out there. Check out our YouTube video that demonstrates some of the carbon we offer. :-)

Answer by: Randy on Aug 16, 2016, 2:29 PM
How do you recommend rinsing the media if you buy the additional cartridge without removing the reactor?
Question by: Kyle on Jul 18, 2016, 8:00 AM
Hi Kyle,
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.
Answer by: Charlie on Jul 18, 2016, 1:50 PM
Could this reactor chamber successfully be used as a second chamber for a calcium reactor?
Question by: Wade Bronson on Jul 17, 2016, 6:57 PM
Hi Wade,
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. : )
Answer by: Charlie on Jul 18, 2016, 1:24 PM
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.
Question by: Flavio DeArruda on Jul 4, 2016, 5:49 PM
Thanks for the question.
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.
Answer by: Charlie on Jul 7, 2016, 8:45 AM
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.
Question by: Chris on Jun 20, 2016, 5:14 PM
Great question!
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!
Answer by: Connor on Jun 21, 2016, 5:24 PM

Answer by: Connor on Jun 21, 2016, 5:43 PM
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
Question by: Danny Katz on Jun 12, 2016, 2:21 AM
Great question.
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!
Answer by: Connor on Jun 14, 2016, 6:12 PM
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.

Question by: Mark Shimala on Jun 11, 2016, 10:12 AM
Great question!
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!
Answer by: Connor on Jun 14, 2016, 4:42 PM
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?
Question by: Jamie Springer on Jun 10, 2016, 10:00 AM
Great question!
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.
Answer by: Connor on Jun 14, 2016, 1:47 PM
Would I be able to mix carbon/gfo in this unit for 120g tank?
Question by: Matt on Jun 7, 2016, 9:00 AM
Great question!
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!
Answer by: Connor on Jun 7, 2016, 6:19 PM
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

Great question! The GFO & Carbon Reactor Kits come with 1/2" Mur-lok Polyethylene Tubing. https://www.bulkreefsupply.com/1-2-mur-lok-polyethylene-ro-tubing.html
Answer by: Randy on Jun 2, 2016, 5:15 PM
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?
Question by: Zac on May 17, 2016, 7:32 AM
Great question!
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!
Answer by: Connor on May 18, 2016, 6:59 PM
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
Question by: Thell on May 2, 2016, 1:50 PM
Hey there!
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!
Answer by: Connor on May 3, 2016, 6:22 PM
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.

Question by: Phil on Apr 24, 2016, 3:21 PM
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.
Question by: nathan on Apr 24, 2016, 2:40 PM
Great question!
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.
Answer by: Connor on Apr 27, 2016, 1:42 PM
Why does my reactor keep filling with air? Extremely loud and I can't seem to get the air out?
Question by: Matt on Mar 21, 2016, 8:22 PM
Great question!
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!
Answer by: Connor on Mar 22, 2016, 10:17 AM
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?
Question by: Eddie on Mar 19, 2016, 7:47 AM
Great question!
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.

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?
Question by: Miguel on Mar 10, 2016, 2:02 PM
Great question!
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!

Good morning,

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 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.
Question by: Christopher Williams on Feb 8, 2016, 2:26 PM
Great question!
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!
Answer by: Connor on Feb 10, 2016, 2:07 PM
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?.

Answer by: Connor on Feb 10, 2016, 6:04 PM
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?
Question by: Brad Freeburg on Feb 4, 2016, 4:46 PM
Great question!
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.
Answer by: Connor on Feb 26, 2016, 9:36 AM
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?
Question by: Steve Crosier on Jan 27, 2016, 5:23 AM
Great question!
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!
Answer by: Connor on Feb 3, 2016, 5:18 PM
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.


Dave Streed
Question by: Dave on Jan 20, 2016, 6:00 PM

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.
Question by: Adam Lawless on Jan 20, 2016, 5:53 PM
Great question!
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!

Thank you

Question by: John huynh on Oct 30, 2015, 9:19 PM
Great question!
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!
Answer by: Connor on Nov 2, 2015, 2:03 PM
Does the deluxe come with upgraded connectors and silicone tubing or do you have to purchase that separate? Thanks
Question by: Tim on Aug 20, 2015, 9:44 PM
Great question!
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.
Answer by: Connor on Aug 21, 2015, 2:35 PM

Answer by: Bulk Reef Supply on Sep 3, 2014, 1:28 AM
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.
Question by: Joe on Apr 10, 2014, 12:14 PM
Hi Joe,
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.

Can this reactor be hooked up to another one> in order to run GFO and carbon separately while using the same pump?
Question by: Raul on Apr 7, 2014, 6:40 AM
Hey Raul,
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.
Answer by: Bulk Reef Supply on Apr 7, 2014, 6:40 AM
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!
Question by: Ivis on Mar 17, 2014, 6:08 PM
Hi Ivis,
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.

Do you sell the O-Rings for this reactor? Mine are wearing out and stretching and I'd like to have a backup... Thanks!

What size filter pads does this unit need?
Are they 3 inch round with a center hole or 4 inch with an offset hole?
Question by: Frank on Feb 23, 2014, 11:49 AM
Hi Frank,
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:

When using gfo in the reactor do u need to use the road sponge pads?
Question by: robert on Feb 20, 2014, 2:52 PM
Hi Robert,
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).

How does the MJ 1200 connect to the reactor. The tubing included does not fit.
Question by: Doug on Feb 3, 2014, 12:36 PM
Hi Doug,
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).
Answer by: Bulk Reef Supply on Feb 3, 2014, 12:36 PM
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.
Question by: Nate on Jan 22, 2014, 2:37 PM
Hi Nate,
The reactor tubing is just 1/2" Polyethylene (RO) tubing. It can be found right here:

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?
Question by: chris on Jan 6, 2014, 5:51 PM
Hey Chris,
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.

What is the difference between the Single & the Deluxe?
Question by: Jack on Dec 30, 2013, 12:06 PM
Hi Jack,
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.
Answer by: Bulk Reef Supply on Dec 30, 2013, 12:06 PM
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
Question by: Hai on Dec 17, 2013, 12:06 AM
Hi Hai,
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.
Answer by: Bulk Reef Supply on Dec 17, 2013, 12:06 AM
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?
Question by: Chris on Dec 2, 2013, 9:26 AM
Hey Chris,
Its just 1/2" RO tubing and we do sell it right here:
Answer by: Bulk Reef Supply on Dec 2, 2013, 9:26 AM
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
Question by: Mark on Oct 31, 2013, 3:47 PM
Hey Mark,
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:
Answer by: Bulk Reef Supply on Oct 31, 2013, 3:47 PM
Can you run both gfo and carbon at the same time?
Question by: Kwame on Oct 26, 2013, 4:25 PM
Hey Kwame,
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.
Answer by: Bulk Reef Supply on Oct 26, 2013, 4:25 PM
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
Question by: gillian on Oct 24, 2013, 9:44 AM
Hey Gillian,
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.
Answer by: Bulk Reef Supply on Oct 24, 2013, 9:44 AM
Can this be hung on the aquarium? Like the the phosban reactor?
Question by: Larie on Oct 13, 2013, 9:11 AM
Hey Larie,
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!
Answer by: Bulk Reef Supply on Oct 13, 2013, 9:11 AM
Will this reactor work with biopellets?
Question by: Abtin on Oct 4, 2013, 2:38 AM
Hi Abtin,
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).
