Good investment By Mark on 8/13/2019Mark would recommend this product to a friendHabe been just getting by with dosing, skimmer, and fuge for a year. Some things would grow slowly, others just existed. I increase kessils by 25% and added this and things seem to have really taken off. My acros have grown more in the past month than the previous 9. Niw if i could just get a good batch of co2 scrubber, I'd be set.
Best Reactor on the market By Roger on 6/18/2019Roger would recommend this product to a friendReceived my BRS Reactor today. And I must say, the set-up for this BRS Reactor was so easy, it's laughable. It only took me 20 minutes from start to finish for the set-up.
I'm so hyped. The plan is to purchase the smaller BRS Reactor for my 10 Nano SW Tank.
This Reactor Rocks By Dan on 6/18/2019Dan would recommend this product to a friendNext to BSR's 4 Stage RODI System, this Dual Reactor is just as easy to setup. Love being able to run carbon and gfo at the same time. Phosphates are finally where they should be. The only thing is, I had to go to Amazon to get the recommended Cobalt MJ1200 pump, it works great.
Couldn’t be happier with my purchase! By Thomas on 2/18/2019Thomas would recommend this product to a friendAfter a free days online the BRS dual reactor has my 90 gallon reef tank crystal clear! Water quality is like night and day! Couldn’t be happier with this reactor! Super simple to install.
Easy to refill By Stephen on 1/1/2019Stephen would recommend this product to a friendEasy to set up, easy to refill, super easy to clean. Glad the inner canisters are clear now you can see gfo tumbling. Great product I connected this directly to a manifold and it works flawlessly. Keep up the good work BRS.
Just perfect By rafael on 12/4/2018rafael would recommend this product to a friendGot it last week.
Super easy to set it up.
No leaks , works for me just perfect.
Super GUUUUUT!!!!! By rafael on 12/4/2018rafael would recommend this product to a friendJust go it last week. Easy to set it up. I love it.
My water clears up in hrs!!!!
A must have By Justin on 11/26/2018Justin would recommend this product to a friendProduct comes with all hardware to get this going. You just need to add GFO or Carbon. Only thing I would add would be recommended size for a tank, but I guess I wont have to fill as often.
Good By Scott on 7/9/2018Scott would recommend this product to a friendWell I got this after I started curing my rock. Did bleach to kill everything do I thought. Checked phosphorus/phosphate and it went stupid flashing 200ppb. Spoke to a few they recommended it with gfo. But in dropped from 200+ to 106 in like 5hrs. It was down to 22 but noticed a rise this last week to 34 ppb. Time to change gfo. So if phosphorus/phosphate is your issue this is a very helpful and important piece of equipment.
Dissapointed By Joe on 5/25/2018Joe wouldn't recommend this product to a friendIt works... and the mj1200 I'd a great pump, the canisters are the same hard quality acrylic as the brs rodi units. I am not happy that the mounting bracket is flimsy plastic. When hung it bends and doesnt even hold the canisters straight. I assumed the bracket would be metal as it is on my brs rodi. Also the plastic tubing is very stiff and almost impossible to flex. Silicone tubing would be a much better choice but apparently that is a separate purchase. For $94... I didnt expect it to be so cheap.
Buy it By TPack17 on 5/5/2018TPack17 would recommend this product to a friendWorks great on all my tanks.
Great Reactor! By Todd on 3/25/2018Todd would recommend this product to a friendI love this reactor. Like my BRS RODI unit, this reactor is built with quality materials and works great. I have always had a little bit of a phosphate issue probably because I’ve always used media bags in my sump but this reactor has done the job. I’m not sure why others say that the pump isn’t strong enough to fill both canisters because I bought the MJ 1200 pump that BRS recommended and it works perfectly. I have the valve open a little over halfway and it’s lightly tumbling the GFO perfectly. I highly recommend this reactor
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.
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.
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
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
Which replacement pads should I purchase for this reactor ?
You would want to use these replacement filter pads:
What is this used for
Looking to buy a couple of the ball valves included with this reactor. I don't see them listed separately on the site.
They are 1/2" inline ball valves. They can be found right here:
I will be upgrading my tiny 14 gallon tank to a nice 50 gallon soon. Is this product recommended for a brand new tank?
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.
What kind of flow should this unit be pushing (gph)? I've got about 300gallons of total water volume and am sitting at about 56gph through the reactor. I've got about 1.5 cups of GFO and Carbon now, as I didn't want to pack them any higher even though they are noted to hold 2 cups. GFO wouldn't be able to tumble based on what it looks like.
I’m setting up a 70 gallon system. Should I run the dual reactor right away. Or wait till it’s fully cycled. I’ll be cycling with dr. Tim’s one and only.
Also I’ll be running the reactor off a manifold where should I put the return line on the sump. My sump set up goes Skimmer, Refugium, then return.
The carbon can start running during the cycle but I would not do GFO until the tank is cycled and you know you have high enough phosphates to use GFO. If you use it with barely any phosphates you will strip the tank.
Hello there I would like to know that.can I use dual go and carbon reactor for my freshwater refugium sump and what type media it should use.thank for helping me.
You certainly can use the reactor and Carbon and GFO with a freshwater tank! Any of the Carbon and GFO supplements will work great at clarifying the water and removing phosphate. Feel free to let us know if you have any further questions!
Will the MJ-1200 be able to push water down 30inches, through the reactors, then up 30inches? Just want to make sure the pump will be strong enough.
The MJ1200 would be a little limited to push back up 30". we recommend an alternative such as a sicce 1.5 which can handle a greater head height. Feel free to let us know if you have any further questions!
I want to use an external pump to run these dual canisters, what size pump will I need?
My dual reactor slowly fills up with air over a day. I have to adjust to zero flow, let the water level rise, then slowly turn on the flow to push the remaining air out. Any recommendations?
The reactor has a small air bleed hole that can be found on the underside of the bracket/lid assembly when the canisters are removed. Most likely it just has a bit of detritus stuck in it. You should see one large exit hole in the middle, and towards the exit side of the reactor a very small hole. Cleaning that out will help the air to bleed out of the system as it runs. That said though, couple of other points worth mentioning.
First of all, if air is finding its way into the reactor you likely need to submerge your pump farther. Sounds like its sucking in air.
Second, and likely most importantly, if their is some air in the reactor it won't effect the performance in anyway. The water is traveling through the system as it should so removing the air is purely an aesthetic thing. It is just for looks, so you could just as well leave it as well :)
In a single carbon or gfo reactor such as the brs brand can I use bio pellets on them or not
I have some questions on the BFS dual GFO and Carbon reactor. Which one is best for my size tank..
I have a 75 G reef with a sump under the tank in the cabinets... I have room for the reactor next to the sump I have limited space inside the sump with my skimmer etc.
So, can the reactor sit outside the sump and how big of a pump will be needed and the dimensions of that pump so I can be sure the pump will fil in the sump...
If you could give me that info I'll get it ordered.
The dual reactor will work perfect and easily can be mounted in the sump or externally mounted to the outside or wall of the stand. If the reactor will be within the 2-3 feet of tubing included we recommend the Cobalt Mj1200 pump which is very small only 4x 2x 4 inches. Feel free to let us know if you have any further questions!
I am in the process of setting up a 150g tall reef. Would these reactors be able to handle this size tank with a medium to mid heavy bioload?
I need some new tubing for my reactor. What size tubing could I buy and ifni could buy them on BRS that would be ideal.
We do sell extra tubing for our reactors. This is sold as 1/2" Mur-Lok RO tubing.
Have a great day!
I just purchased the BRS GFO & Carbon Reactor but I am wondering if the flow is the same for the carbon as it is for the GFO how can I ensure that the flow will not push the GFO out into my sump?
The flow will typically be base off of the GFO requirement. You will place the sponge at top to prevent GFO from flowing through. Ideally the GFO will tumble smooth without being forced to the top. Feel free to let us know if you have any further questions!
Hi I have a red sea 350 reefer (93 G total) I want to run gfo and rox 0.8 carbon what reactor would you recommend is the better choice.
1. BRS GFO & Carbon Reactor – Dual
2. BRS GFO & Carbon Reactor - deluxe
When using the ROX 0.8 carbon you can select either and they will work great! You will use around 1/2 cup of media an the reactors can handle twice that amount. If you are planning on using GFO as well the dual will be nice as you can change the Carbon and GFO at different times. Feel free to let us know if you have any further questions!
I am trying to locate extra media cartridges for this unit. Thanks
We do sell extra media cartridges for this reactor and they can be found at the link below. Have a great day!
I have just a single carbon reactor now and I want to switch to the dual reactor is it ok to run the gfo all the time like I do with my carbon? Still new to all this so I just keep researching.
GFO will be run very similarly to carbon however ideally it will be tumbling. You will change the carbon once every 4 week and GFO once every 6-8 weeks. Feel free to let us know if you have any further questions!
I am currently running a dual reactor with GFO and carbon. I am considering running bio pellets instead. Would it need to Br modified and what would you suggest I run in the second chamber?
Thanks for your help
Depending on your system size we do not recommend running bio pellets in the standard dual reactor. This would clog very quickly and not feed the correct number of pellets. We recommend a dedicated bio pellet reactor instead.
I was interested in getting a reactor for my 90G reef tank. Which reactor would you recommend? The single or the dual?
Assuming you want to run GFO and carbon you would want the dual reactor for a tank that size. If you just plan to run a single media, then the single would be fine.
I been using it for a week and I don't see my water look clean The flow it's got to be very low so the gfo don't go into my tank oh good may fix the problem
Great question. When dealing with water clarity it can vary greatly depending on the elements in your tank. If the water contains green water (Algae) It will be tough for the Carbon to remove any of the colors from the water and a large water change will need to be performed. With the GFO often you can attempt to add an additional sponge in the top to help catch any GFO particles from flowing into the tank. If the issues continue feel free to give us a call and we will be more than willing to help!
Can you use seachem’s denitrator in the GFO canister?
I currently own this reactor and really like it! I noticed it resembles a simplified RO/DI unit and was wondering if it's possible to convert my old RO unit into another reactor similar to this one. (I try to recycle and reuse old equipment as much as possible
OK Im needing the orings for this unit and couldn't local it can you send me a link by the way love the unit
I have the BRS Dual Reactor do you have a plumbing adapter that will take the hose the is supplied with the reactor and attach it to 3/4" PVC plumbing so it can be added into my existing plumbing?
Schedule 80 Reducing Bushing 3⁄4” Spigot x 1⁄2” Slip
1⁄2" Male NPT x 1⁄2" Push Connect
Just cleaned the dual reactor started it up not working correctly. There is a lot of air in it. How do I fix this ?
I have a 264 gph submersible pump, would that be enough to work for this?
As long as it has a reasonable amount of power it should be just fine.
Could a eheim 1000 work for this?
This could work however the Eheim pump connects to 5/8" tubing which will be very very difficult to convert to the 1/2" OD Polyethylene tubing on the reactor. we do not currently have any adapters or components to make the connection. Feel free to let us know if you have any further questions!
Will the pump that comes with this reactor work for a 500 gallon tank? Or is it best to use it in the sump?
what size tubeing is in kit thank you
The dual reactor comes with 1/2" tubing. Have a great day.
I would like to run these online with a UV light, is that ok to do and what pump would I use?
I just purchased one of these and was wondering if I could hard plumb it from my return pump instead of using the pump it comes with.
Have a great day!
Does the Gfo and carbo duel reactor come with the tubing to hook it up? And can you run carbon and Gfo at same time ?
In the Dual reactor the plumbing and all components will be included. With the Dual it is recommended to run the GFO in the first chamber and carbon in the second chamber.
Can you run Phosgaurd in these?
Thanks for getting in touch with us in regards to using Phosguard in our reactors. These would be great for use with Phosguard. Please let me know if there is anything else that we can assist with. Thanks!
How would you go about hard plumbing this? I assume unscrew the push---->mpt fitting and insert pvc fitting i there? What size would that be?
If you would like to hard-plumb your reactors, you can certainly plumb directly to the canisters using 1/2" npt fittings.
Have a great day!
I'm going to need longer tubing due to it being placed underneath my tank. What size tubing do I need? What else will I need such as elbows to route the cords better?
The tubing is 1/2" RO tubing which can be found at the link below. Fitting wise, it depends on your setup but elbows are largely it. Perhaps a 1/2" union if you need to connect two pieces together in a straight location (but its usually cheaper just to buy a longer length of tubing then to buy the fitting to connect two together).
Hi im having a high phosphate and nitrate problem and its causing algea in my tank. I dont have a sump. Im new to this all. This is what is needed to helo lower them right? And i was buying the reactor dual with the pump combo. What else will i need for full setup. Want to mount it in the cabinet below aquarium. And not sure what stuff
Goes inside it. Do i need all gfo and if so what kind of gfo?
The Dual reactor will work great to run carbon for removing color, and odor from the water and GFO for removing phosphate. This is one of our favorite set ups to keep the system running!
Not much more will be needed beside the GFO and Carbon. For nitrate control the best will be regular water changes however there are several options for nitrate control available. Feel free to let us know if you have any further questions!
I have read all the info available for this piece of equipment, and i have read all the questions trying to understand why, but what exactly makes this reactor incapable of running high quality carbon in the first chamber and bio pellets in the second? it looks like the same type of construction on your specific bio pellet reactor, and i would like to better understand the differences!
We do not recommend bio-pellet in the reactor for several reasons. In the second chamber the flow is greatly reduced (the whole unit if placed in the first chamber) The flow on a stand alone bio-pellet reactor is best adjusted independently from carbon and GFO to keep from adding too much flow or too little which either makes the pellets clog or release too much food into the tank. Feel free to let us know if you have any further questions!
I see you sell extra cartridges for hte 5 inch reactor, do you sell extra cartridges for this 10 inch reactor?
We sure do! You can purchase replacement hard-shell cartridges for our reactors at the link below!
I believe I've gone through all the questions but I haven't seen an answer to mine. Is there a way to flush out just the GFO? Would flushing out the GFO through the carbon clog it up? Or should the GFO be flushed out separately before adding to the reactors?
Whether you are using one media or both, it's totally fine to flush your media prior to running on the tank. We prefer to do so after the media is inside of the reactor by turning it on and running the initial output into a bucket. We demonstrate this briefly in a video at the link below.
https://www.youtube.com/watch?v=ezQfrJeVZXQ (media flush is around the 4 minute mark).
Hope this helps!
Hi - I am looking to replace my phosban reactor that keeps leaking and is difficult to clean. The BRS system looks great, but what are the major differences between the standard version and the deluxe versions you produce? Thank you!
How much carbon and gfo for a 125 with a 40g sump
From my calculations, you would need about 2 cups of Standard GFO and 0.81 cups of ROX 0.8 Carbon.
So I bought the dual reactor and I'm putting a 3 stage sump on my tank. What part of sump should I put the feed pump for the reactor and should I feed it into the refugium section or into the final stage of the sump? Thank you for your help!
I ordered this and the connectors leak where the tubing goes into the reactor. Am I doing something wrong ?
I am sorry to hear about the reactor leaking, You most likely are not doing anything wrong however the connections sometimes need to be removed and reinserted to make a proper seal with the quick connect. If the issue persists feel free to give us a call and we will be more than willing to help!
Can you use purigen in one chamber instead of carbon along with gfo in the other chamber? How would that affect a 75g reef?
I have a fish and reef tank 45 g/ fluval 206 canister filter/ Octo skimmer, but no sump. Running for 3 years. Can this be set up under tank and does it come with tubing set up for that? I'm planning on upgrading to a 125 or 150 g in near future so will this still be effective in a larger tank as well?
Can pump be installed on either side of Reactor?
Does it matter which media flow hours through first?
How does it flow through each, outside down to bottom then up middle?
The reactor has labeled "IN" and "OUT" ports but you can flip the bracket if you require the feed pump to be on the opposite side.
It does not matter which media is placed in the first canister but many people find it easier to tumble their GFO by placing it in the first canister and holding their carbon between sponges in the second.
When run as recommended, the water flows into the reactor, down around the outside of the refillable canister and then up through the bottom of the canister.
I have a 200 gallon tank and was wondering if this dual reactor will be enough capacity to hold both GFO and Carbon to make it beneficial towards filtering my tank.
Unfortunately the dual reactor would be a little small however could work with ROX 0.8 carbon and High Capacity GFO. On a larger tank such as 200 we recommend more room in the reactor with the Jumbo BRS reactor or even the Phosban 550. Feel free to let us know if you have any further questions!
Hello, i need replacement sponges and screens for the Bulk Reef Supply dual reactor. Do you sell these? What item number is it?
We do have replacement pads available (Listed in the link below). Unfortunately we do not have replacement screens available. Feel free to let us know if you have any further questions!
I have this reactor. I find it really hard to disconnect the tubing from the push connect fittings. I need to disconnect the tubing whenever I change media so I can connect a longer outlet tube to drain into a waste bucket. Is there a trick to disconnecting the push connectors? I know you have to push in the connector but it is hard. I tried cutting a ring of pvc pipe to fit around the tubing to use to push in the connector, that helps a little, but it is still hard. Do they make a tool to do this?
I have included a simple link below for the instructions on removing the fittings but it sounds as if you already know the general way to disconnect them.
I have included a few items below which can be added to the tubing to make it easy to disconnect which not dealing with the mur lok fitting.
1/2" Female Thread Cam Lever Coupling - D
1/2" Female Thread Cam Lever Adapter - A
1⁄2" Male NPT x 1⁄2" Push Connect ( you will need 2)
Hello. Does the water through the GFO container and the one flowing through the Carbon container have the same flow rate?
Yes they are connected in series and will both have the same flow rate.
So my question is about routing the plumbing.... Is there a right or wrong way? I have a sump and I have it it coming out of the return side of the sump and have it going right back in the same chamber.... Is this bad or could there be another way? Also I have a maxi jet 1200 powering it.. But it's wide open and doesn't seem to be tumbling hype gfo very much... Any help would be great... Thank you.
There isn't really a right way or wrong way here. Your going to cycle the tank over so many times over the coarse of a day, week, etc that I would just plumb it in the most convenient way possible. Generally this is going back to the same chamber you pumped it from as then you don't have to worry about any odd siphoning issues or anything like that. Your looking for the least amount of flow that keeps the GFO from turning into a big brick, so long as it hasn't solidified into a block your good to go :-)
My question is if you have to put the reactor inside sump or could you get away putting it outside the sump since I don't have enough space for the reactor inside the sump.
The reactor can be placed anywhere in the sump or out of the sump. It is sealed and will not leak if mounted externally. Feel free to let us know if you have any further questions!
Hi. I have a 200g mixed reef tank but I feed pretty heavily since I have some big tangs. My phosphates have been pretty high and can only put in 1.5 cups of the high capacity GFO so it tumbles properly. Can I put in this GFO in the carbon chamber as well and run double GFO with no carbon? Thanks.
While it is possible the flow rates would be different from chamber to chamber and impact the performance. ideally separate pumps or a larger reactor will be needed.
Could you use a carbon block instead of the granular carbon in the carbon part?
Due to the great deal of pressure needed to force water through the carbon block this would not be possible with an ordinary water pump. Also, the small pore size would quickly clog as detritus from your system was pumped through the block. I would stick with one of our granular carbons.
I hope this helps!
Have a great day :)
Is it possible to make this reactor have separate flows to each chamber so to tire each media different. I hope that makes since. Also is it possible to use a a different media other then GFO for the removal of phosphates.
You can attempt to move the position of the canisters to adjust so they are not next to each other if needed. Other medias can easily be used in the reactor without issue. Feel free to let us know if you have any further questions!
Would you be able to run a combo of GFO and carbon in the first chamber and biopellets in the 2nd? Or would you need to have 2 separate reactors for this? Thanks in advance.
You will not be able to run Bio pellets in the standard carbon or GFO reactors. They will be a bit of a head ache and clog very quickly. Feel free to let us know if you have any further questions!
What size tanks are these rated for?
These will work on a wide variety of sizes depending on the amount and type of media used. Up to 200+ gallons when the High Capacity GFO and ROX 0.8 carbon are used. Feel free to let us know if you have any further questions!
Is this big enough for a 90 gallon aquarium?
This will certainly work well for a 90 gallon system. Feel free to let us know if you have any further questions!
I need to replaced the elbows on the reactor what size do I need?
I need replacement O-rings for the BRS GFO/Carbon media reactors - do you sell them? If not, can you tell me what size they are?
Can you use this without a sump?
I have a couple of questions. First, the height listed. Is that the height of the canisters only or does that number include the bracket? Also, do the instructions tell you how much media is needed for your size tank? I have a 40 breeder. Thanks.
The height is total. The amount of media you use isn't dependent on the reactor (though it has a max capaicty). The amount of media you use is dictated by the size of your aquarium and what actual media you are using. Instructions would be on the container of your media, but you can use the BRS calculator on the website to calculate out the amount for any of our BRS brand medias ahead of time. You can find it at the top of the page or at the link below:
Hi, I've been having problems with mine leaking at the 0 rings. Do you have replacements for the rubber 0 rings?
Thanks for getting in touch with us in regards to your leaking reactor. We do have replacement O-Rings for those canisters. I have included a link below to this item. Please let me know if there is anything else that we can assist with. Thanks!
Bought the Dual reactor a couple months ago. The GFO is a little too much for the tank right now, (I want some chaeto to help with the Pods in the tank) so I will be pulling the GFO out, but still want to run carbon. Can I add double carbon in the GFO side just to extend the time between carbon changes, or is that a bad idea?
Its not problem to run the GFO chamber empty but it wouldn't be useful to add twice as much carbon. It would still need to be changed in the same amount of time so it would really just be a waste :-)
Where would you place this in the sump? Would you want the return line running into the return chamber of the sump?
You can place this anywhere, most will place the pump in an earlier section of the sump and the drain from the reactor into the return section. Feel free to let us know if you have any further questions!
I have a 300 gallon tank with about 80 gallon sump refugium. I am need to decrease nitrates, and possibly phosphates(as the green film is starting to show up on the glass more often) . Would this dual reactor work with sulphur in one and argo(calcium) in the next? I am wanting to replicate a sulphur reactor. Or would you just recommend something else?
You can use the dual for GFO and carbon really well! However for sulfur you will want a dedicated nitrate reactor ( to keep the correct flow and gas release). I have included a link below! Feel free to let us know if you have any further questions!
Hey am still new to the hobby. I am looking to purchase the reactor with the sicce pump. What media do you recommend and is there anything additional I need to purchase? Could I use this in the future to add nitrate removal pellets
You would need to add a carbon and GFO of your choice. We do not intend this to be used with any other kinds of media.
I bought the brs 2 chamber rector. The gfo/carbon. I have a top fin power head 50. Qmax:171.73 gph max height is 4.75ft the pump is only going to push it up 2ft is this enough power or will I have to purchase a new pump.
Instead of running GFO and Carbon in a 2 stage BRS reactor, can i run carbon and phosguard?
That will work just fine with many types of media. Feel free to let us know if you have any further questions!
Do you carry replacement sponges?
Here is a link to the hard shell reactor replacement pads.
Have a great day!
Hey I'm looking into buying this for my 120gallon mixed reef but u need to know the dimensions of it, my sump is pretty large, but I don't have a lot of space to mount inside the cabinet so I'm hoping to just place it in the sump. Thanks
With tubing installed and bracket the system will take 11" wide, 15" tall and 5" front to back. Feel free to let us know if you have any further questions!
I need to buy replacement o-rings for the canisters. Do you sell them?
Thanks in advance for any info.
Can I run biopellet in here, in both canisters
Is it possible to hang on back of display tank?
You certainly can! Just use the pump in the tank and it will pump water up and over your glass, through the reactor and back into the tank!
I saw on one of the forums that, the cobalt MJ-1200 that you suggest for these reactors is very loud. If that is the case, can you suggest what size pump(GPH) would be a suitable replacement? My system is super quiet and I would like to keep it that way. Thanks.
Those folks are confusing the pump with the Marineland Maxi Jet 1200. The marineland pump used to be the go to standard however they took the design to China and ever since those pumps make a very loud rattling noise when used in a reactor or other situation with back pressure. The cobalt aquatics MJ1200 is the old original italian made pump and is the same tried and true quiet and reliable pump we were all used to and the one recommended for the reactors.
Can i run this dual reactor using one of my extra valves from my return pump as i install extra gate valves? or do ii have to use a separate pump?
The dual reactors can be run off of your return pump. You will just need to convert down to ½” female NPT threads and then with the fitting in the link below (sku 100003) will thread into your return plumbing and allow the push connect tubing to be used with the reactor.
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?
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.
Do you sell the sponge disks that hold the media in place separately?
I think these are what your looking for:
Could i run the duel gfo and carbon reactor with biopellets in one chamber and carbon/gfo mixture in the second, or would the pressure the biopellets need to tumble be too much.
The dual reactor is not compatible with biopellets. As much as we would wish otherwise, biopellets do not play nice with other medias and need to be run in an entirely separate reactor :-)
What size carbon can use on dual reactor. U have multible. What gfo
Most folks use the lignite carbon in the reactor as its easy to work with in that setup. As far as GFO goes, most people use the standard GFO. The only reason to use the high capacity GFO would be if you need more then fits in the 2 cup capacity of the reactor, because the HC is twice as dense it goes twice as far for the same volume.
Is there any way that I can hang this on the back of my JBJ NANO 28 gallon?
Unfortunately the dual reactor doesn't have a hang on back configuration. It could either be mounted to the wall,stand, etc behind the tank or even just set on a desk. If you need something that has the ability to hang on the rim of a tank then I would look at the Two Little Fishies Phosban Reactor. It has a hang on back mount. The 150 will have plenty of capacity for a tank your size.
I have a 150 g tank with a 25g sump below the tank, is this a large enough unit and how often would I need to change media, no phosphate problem now but looking to add fish and corals, I have 6 fish now 3" long. Thanks
The reactor has a fixed capacity (two cups of media that needs to tumble, like gfo, and 3 cups for media that doesn't, like carbon) so how big it is really depends on the media you plan to run and how much you need. What medias were you planning to put in the reactor?
Hi, I have a 120 gal tank, with a 30 gal sump. would it be wise to run this unit with both mixtures of gfo/carbon in both canisters vs. gfo in one and carbon in the other?
With the dual reactor its best to run GFO in one and carbon in the other. GFO generally is changed less frequently then carbon when its feasible (usually monthly) whereas carbon is changed every 2 weeks. Keeping them separate allows you to do this :-)
Interested in the dual phosphate/carbon reactor. Have 100 gal tank with sump, which pump do you recommend? Thanks
We recommend the cobalt mj1200 for use with the dual reactor. It plugs right in, works well, and tend to last a long time.
Can I run bio pellets in the first chamber and a mix of carbon/GFO in the second?
The dual reactor is not compatible with biopellets. For biopellets you would want a separate biopellet reactor. The BRS biopellet reactor works great for tanks under 50g, otherwise something like the octopus BR series reactors are usually the next size up for folks.
We have several BRS media reactors that we use interchangably with bio pellets, activated carbon, and gfo. I was looking on the site today to purchase two more, and see that the gfo and carbon reactor is not for use with bio pellet media. My question is what is the difference between the gfo/carbon reactor and the bio pellet reactor?
The GFO reactor cartridges have sponges (which can be removed) vs the biopellet reactor doesn't have sponges but does include an additional larger fitting for using with bigger pumps as typically biopellets require higher power pumps.
I have 185 gal reef tank (SPS, LPS and soft). Would this dual reactor work? I do 20% water changes every 2 weeks. Only parameter that is off is phosphate at .22.
I have 15 medium size fish.
The capacity of the reactor chambers is 2 cups for GFO. For a tank that size it would work if you were using the high capacity GFO as you would only need 1.5 cups. If you were using the regular GFO you would need 3 cups and then it would not work (then you would want to look at something like the Jumbo reactor or a different manufacturer reactor like the Vertex).
