Quick Overview

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.

  • Excellent product By Jerry on 11/2/2017

    I have a 50 gallon reef tank and this was the perfect reactor for that size tank. I have limited room in my stand cabinet and this fit on the wall just above my sump. It was easy to plumb (I read other reviews saying how difficult it was) the white tubing that comes with it is rigid but was easy to cut with a PVC ratchet cutter ($10 at a home store). I actually like the rigid white tubing as it does not flop around. I ordered the kit with the pump and the union fit the pump discharge perfectly. The pump is quite and I adjusted the flow with the included ball valve per the instructions and everything is working well. This was my first purchase with BRS, the products seem very high quality and a great value. I will be back purchasing more products in the future.
  • Soaked and cut my finger but got it working :) By Jello on 6/5/2017

    Omg! I was expecting this to be pretty simple but it wasn't. Once I got it all connected I started it up and water works all over the place. Then as I quickly tried to get it under control the rigid hoses broke a panel in my sump that ended up cutting my finger. The fish don't seem to mind my blood. That's kind of scary. Anyway, more instructions could have come with the unit. Also it was missing the foam pieces. Only came with one. If you are going to use the connectors included throw in a connector wrench. Other products that use these connnectors throw in that little wrench.

    I am disappointed as this is my first purchase and instead of it being easy and inexpensive it cost me more to fix the damage.i
  • Leaky By Laura T. on 5/5/2017

    Just purchased the mini reactor and hooked it up. I cant vouch forbthe end results as far as water quality just yet BUT i have to agree with what others have said about the tubing being way too rigid. Its very difficult to manuver. Also the most important issue so far for me is that the in and out elbow fittings both leak on and off even when im not fiddleing with the tubing. I would prefer to mount this somewhere but no way it leaving the sump with leaky fittings. Pretty disappointed. Brs has such nice quailty stuff.
  • Just as I suspected By Nick on 10/17/2016

    This thing is a beefcake. Same simple yet sturdy design as the normal size reactor, but in a smaller form. The small foot print is a huge plus in the reefing industry because of all the new toys that come out. Functionality and performance are top notch. Would highly recommend this reactor.
  • Great Product By Gb on 10/12/2016

    This is a really well made product. Its sturdy. Tightens and Un-tightens easily. I use this for my Gfo and Carbon mixed together and it works great.

    Only two points.
    1. Wish it came with a couple extra sponges. With only one sponge the media inside the reactor now tends to push the sponge up. Therefore there is some tumbling going on with the carbon and gfo mix. A couple extra sponges allows you to hold everything in place better. Or allows you to replace the one thats in there now which is getting old.

    2. If there was an option of semi-ish-flexible tubing as well. The white tubing is really ridged and in smaller sumps is hard to move about and position nicely in between other equipment and is in the way sometimes.

    That being said I would Definitely recommend getting this as it really works well, and you will see a marked improvement in your water quality especially when coupled with the BRS higher quality carbon and GFO.
  • PERFECT! By Scott on 6/29/2016

    I must say i absolutely love this mini reactor!!! Included instructions are so short and sweet, it sets up in minutes! I used this in my mini reef tank (20gal breeder) i just set it up in my sump filled it with BRS ROX 0.8 Carbon and BRS High Capacity GFO and my water was crystal clear in about an hour! This is a must have for a new reefer or anyone with a small tank!
  • SIMPLE -- Works, & Effective. By Tim on 6/28/2016

    Very simple, works well.

    I use this with a 29g BioCube that's an SPS dominant reef with Zoa's on the bottom. I do weekly water changes, run an AquaMaxx Hob 1 skimmer and keep my water clean. This seriously brought it to another level, crystal clear water and a good response from my corals.
  • Carbon and GFO By William on 6/3/2016

    Water flow is LOW so im not sure how much of a benefit this reactor is. I will be looking for alternative reactor.
  • Works just like it says it does By James on 5/26/2016

    I've had this for a year now and I've never and problems with it. I read reviews about how they don't like the hard tubes that it comes with or that the connectors leak or that it doesn't tumble. The tubing is fine if you're using in/near a sump, if not, get different tubing. The connectors, like all push fitting connectors aren't meant to be disconnected and connected contently. It makes it easier if you need to make changes but the little rubber seal will wear down if you disconnect these to change the media every time. It's also not made to tumble, as it says. It's a really nice "reactor" for small spaces. the only thing I think it should come with that it doesn't is a filter for the pump. Using this without the pump filter is just a huge headache. It will clog in no time. Get the two pack, they just pull off and push back on in two seconds and you don't have to worry about clogging the canister.
  • Did the job until the first time I had to replace media then developed terrible leaks By none on 3/20/2016

    This product needs to be reconsidered. The ridged tubing it came with was completely useless. I ended up replacing it with flexible tubing from a hardware store. It worked fine until I had to replace the media. After the replacement both connectors on either side leaked. I tried all kinds of methods to resolve the issue, but the leak never stopped. The leak issue makes this product useless. The connector method needs to be re-evaluated.
  • Nice product By Pastelball on 3/7/2016

    This reactor is nice. Easy to setup and great for small places.
  • Great for small tanks By FlyinBryan on 3/1/2016

    I suspend the jbj pump in tank to prevent vibrating noise. I mix go & carbon in chamber. I change out like once a week, it's a 5 minute process. All the tubes, hosing, pumps, and build quality, every7is just top quality.
    My tank is pristine all the time!

Product Questions

Will this reactor be good as a GFO+Carbon reactor for a small pico tank (about 2.5 gallons)? The tank sits on the kitchen counter....could I put it directly behind it or will it work best if it is under the tank somewhere?
Question by: Mark Shimala on Jun 26, 2016 5:55:00 PM
Great question! You will have to have a pump somewhere in the aquarium to feed the reactor, which may be an issue for space. Honestly, with pico tanks, I recommend a vigorous water change schedule. :-)
Answer by: Randy (Admin) on Jul 1, 2016 11:36:00 AM
Can I use the mini reactor to run bio pellets? I know you have a bio pellet specific reactor, but its a little large for my application.
Question by: Steven on Mar 30, 2016 3:30:00 PM
Great question!
The Mini Reactor will be very difficult to use with Bio-pellets, the reason is the pellets will clog very quickly due to the shape and design of the reactor body. We recommend a reactor designed specifically for Bio-pellets whenever possible. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 4, 2016 10:16:00 AM
I want to run this with a mix of carbon and gfo and a different pump. How much flow should be supplied to this reactor?
Question by: Griffin on Mar 30, 2016 5:25:00 PM
Great question!
Ideally this Will work on a max flow around 300 GPH, typically between 150 to 200 works great depending on the head height. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 30, 2016 6:50:00 PM
Hello, can I connect the reactor to my sumps out return pump using a splitter, or do I have to purchase its own separate return pump for it to work more efficiently?
Question by: Isaias Vieyra on Apr 27, 2016 1:55:00 AM
Great question!
You can choose to either split the return pump or use a separate pump. Both options will work well!

Can phosban media be used alone or does it need to be mixed with carbon? Biopellets?
Question by: Isaac on Jan 27, 2016 8:56:00 PM
Great question!
The phosban media can be used alone. It is not recommended to tumble media in the mini reactor as it is too small and may allow for clogging. there is not a need to mix Phosban with other media. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Feb 4, 2016 3:26:00 PM
Hi, Up to what size tank do you recommend for this reactor
Question by: Ray eutermarks on Oct 24, 2017 7:23:00 AM
Hi Ray, thanks for reaching out!
The size of system is going to depend on what type of media you are using. The reactor holds up to 3/4 cup of media.
3/4 cup of ROX carbon for instance will treat a 120 gallon system
1/2 cup of High Capacity GFO which leaves room to tumble media, will treat a 65 gallon system.

Check out our reef calculator to see how many gallons your chosen media will treat.

Hi, I have a bio cube 29 and I want to install this in the stand. Would the pump be strong enough to bring the water back up and also strong enough that I could just replace the return pump and use 1 pump?
Question by: Chris on Mar 8, 2016 10:13:00 PM

How many cups of media (will be using for carbon) will fit in the mini?

Are there any drawbacks to using the mini for both carbon and GFO?
Question by: Eddie on Dec 21, 2015 7:42:00 AM
Great question!
The mini will hold 1.5 cups of media. It can be used with Carbon or carbon and GFO mixed together just fine however is too small for only GFO as it would clog. Feel free to let us know if you have any further questions!
Answer by: Connor Johnson (Admin) on Jan 6, 2016 5:55:00 PM
Hey! I'm pretty new to the reefing hobby. I had a 55 gal years ago. Nothing too special. I've just purchased a 125 gal with a 20 gal sump tank to start the hobby again. This is my first sump. I've been watching the BRS 160 videos and love them! So thanks for that! I wanted to know if the BRS mini reactor would work for my size tank? I'm sure I have plenty or more questions to come. Thank you for your time!
Question by: Carla Patterson on Dec 21, 2015 12:16:00 PM
Great question!
The mini is able to hold around 1.5 cups of media and would be too small for a 125 gallon tank. For that sized tank you will need the standard reactor. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 6, 2016 5:58:00 PM
Im building a mini tank 20gal display and 10gal sump set up. can i use this reactor to run my Carbon and GFO? or is my tank too small for it?
Question by: Scott on Jun 20, 2016 8:57:00 AM
This will work great for a system of that size! Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jun 21, 2016 5:34:00 PM
If I wanted 2 of these would a single mj1200 pump be enough flow to make it through both of them and back up to the tank. This would go in the cabinet of a IM Fusion 20 and have to travel back up to the tank.
Question by: Josh on Aug 26, 2016 9:21:00 AM
Great question! I wouldn't recommend trying to use the MJ1200 to pump water down to the reactors and back up to the top of the tank. I would recommend something more along the lines of the Sicce 0.5 or the Sicce 1.0 to handle that head height. :-)

How can I get a extra o ring for the mini reactor
Question by: Terry on Feb 1, 2016 1:32:00 PM
Great question!
We do have replacement O-Rings which are the same as our other canisters. I have included a link below.
https://www.bulkreefsupply.com/o-ring-for-10-reverse-osmosis-canisters.html
Answer by: Connor (Admin) on Feb 10, 2016 5:02:00 PM
Would one MJ1200 be able to provide enough flow through 2 of these mini reactors, using either a T/Y adapter or running the output from one reactor into another?
Question by: Nick on Dec 23, 2015 8:34:00 AM
Great question!
The MJ1200 can work great with 2 reactors. by connecting the tubing is a fairly easy option. The only issue is if you are planning on running GFO it will need to be mixed with Carbon on the Mini as the GFO will clog very quickly by itself in the Mini reactor. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 7, 2016 2:27:00 PM
What is the largest aquarium size that I can use with this reactor ?
Question by: Miguel villalobos on Jan 21, 2016 9:41:00 PM
It will vary depending on the media used however typically the largest will fall between 60-75 with the high capacity GFO and ROX 0.8 Carbon. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 27, 2016 8:03:00 PM
Would this be large enough to use as a carbon only reactor on a 60 gallon?
Question by: Matthew Goldberg on Apr 19, 2016 8:06:00 PM
Great question!
If High Capacity GFO and ROX 0.8 Carbon are used it can work. However standard GFO or Carbon will need a larger reactor.
Answer by: Connor (Admin) on Apr 26, 2016 12:56:00 PM
I have a 90gal mainly fish only will the mini be ampl size for my tank?
Question by: Wil on Apr 8, 2016 9:13:00 PM
Great question!
The mini would be a little small and not hold enough media. We recommend the standard reactor instead. Feel free to let us know if you have any further questions!
