A purchase you won't regret By Glenn on 5/12/2013
Glenn would recommend this product to a friend
This is my first reef tank and I had absolutely no problems setting this up in a matter of minutes. The product is well-built and has been keeping my water clear and phosphates at 0.00. The cobalt maxijet 1200 pump is definitely the way to go. Extremely quiet operation. From what I hear they're Italian made very reliable as well. I would not hesitate to buy this product again or recommend to a friend.

Just purchased this reactor and it is easy to set up and works like a champ. Clearing up the algea in the tank immediatly.
great simple effective design By christopher on 5/3/2013

i picked this reactor for its convenience of use and accessibility. no complicated seals or valves to mess with. the plastic vessels are thick and the bracket is very sturdy. feel confident with it anchored to a stud. would buy again and most likely will because its American :)
Works but under powered By Chase on 5/1/2013
Chase would recommend this product to a friend
Like other reviews have said I like the reactor over all but it is under powered for my 180g system. Constantly getting clogged in the sponges, I even did it without the sponge and it clogged the bottom vents. Looking for another type of pump to power it, until then i have taken it off line.
it is worth it!!!! By dimitri on 4/18/2013

I was having phosphate issues and my water was not really that clear so i went searching for a reactor when i looked on youtube and saw the Bulk Reef Supply Dual Reactor and the review by two guys that are part of BRS it really convinced me that the DUal reactor would solve my problems.So I ordered it even tho on the video it said it was only good up to 120 gallons, I disagree I have about 135 gallons running through my 125 gallon LPS dominated reef tank and by the end of the first week all of my cyano bacteria vanished and within 3 week all the hair algae i had had been eradicated, and beside running GFO which i bought from BRS i also used the other reactor for carbon and it is wayyyy better than putting two bags of Chemi Pure in my sump. totally worth the 50$ plus i modded it to fit and old pump i used for my nano so no need for there pump if you have a small one lying around. I only used 1 cup of carbon and one cup of GFo my first time and it has only been about 3 weeks since adding them and it made such a HUGE difference. i could notice in less than a day the difference it made.
Great initial response, inadequate pump. By Dalton on 4/16/2013
Dalton would recommend this product to a friend
Pump worked great when i played around with it in my tank but it seems like when attached to the BRS dual reactor it is just to under powered. Reactor itself had no issue and was accompanied with great instructions.
Great quality but limited on connections By tyvek on 4/11/2013
tyvek would recommend this product to a friend
Love the idea and variety that can be used. But had no way to connect any one of 3 different pumps to it? If it is dependent on "john guest" fittings then share the wealth and include an adapter or two...seriously.
For small systems(100 gallons or less) the maxijet that luck of the draw fits then okay. But for anyone else with more throughput and the reactor flow supports it then a slightly bigger pump would beneficial.
With a 15+ reef have had enough improvising and engineering to fill a small book.
Awesome, easy, versatile By Coldjoker on 4/10/2013

Was setup and running within 15 mins, got my GFO at a slight tumble, checked 24hrs later same rate. Don't hesitate "Buy It Now" ;)
works well for medium systems By Andy C on 4/8/2013
Andy C would recommend this product to a friend
I'm running carbon and GFO, 1.5 cups each, for a 200 gallon system and change each every two weeks. I had to upgrade the maxijet to a 500gph eheim pump to prevent clogging, mostly because of the carbon. Eventually I would like to get a seperate one chamber reactor for carbon and then use this dual just for GFO, 1.5 cups in each chamber changed monthly. Right now it works, though.
I do run it opposite of the label, carbon in chamber one and GFO in chamber two. Running GFO first clogged the sponges for the carbon within a week. With carbon first, it flows great for at least two weeks.
Great kit By Fragaddict on 4/3/2013

Great duel reactor kit. Right out of the box it has everything needed for install other than mounting screws. I would like it more if the plastic hose was bit more flexible.
Good so far By Chase on 4/3/2013
Chase would recommend this product to a friend
Purchased this to run carbon and GFO in my first salt water reef tank. So far so good. I mounted it to the wall; the bracket made it very easy. The tubing it comes with is very bent and hard to get straight, but other than that, it came packaged nicely and is working well so far
So far so good By Jeremy on 3/31/2013
Jeremy would recommend this product to a friend
So far works as it should. Pump seems to do the job so far but I personally wish I would have purchased a more high quality pump separately. Also if the hoses are wiggled at all in the fittings water will leak from the fitting otherwise watertight. Over all a great product.
Pretty Good By cdbstl76 on 3/27/2013
cdbstl76 would recommend this product to a friend
I like this product. I had the single, and did a mix of GFO on the bottom and Carbon on top. It worked OK, but there was too much getting clogged. Running this dual chamber is much more efficient. I don't understand the complaints on flow from the pump. The most efficient way to remove compounds is pro-longed contact time with the medium. I have mine running at a little under 3/4 on the valve. This works very well for me. I really like this product!
Pump By Farm boy on 3/25/2013

I was very excited to receive my dual reactor with mj 1200 pump. I was really disappointed with the pump. Maybe it is my fault for not researching the pump. I assumed that bulk reef supply would bundled it with pump you can just attach it to the tubing like on my Next Reef MR1gfo reactor.
Nice build quality By Brad on 3/25/2013

Very nice quality. I would be nice to see a more compact version for people with tight spaces or smaller aquariums. It would also be nice to have the option to add extra push to connect fittings to connect to my pump manifold.
works great. By chris on 3/24/2013

Finally bought a dual reactor to take the place of my phosban reactor so I could run carbon seperate instead of mixed in with gfo. Love it and the pump that comes with it is perfect.
Quiet, Easy to Use By Kathy on 3/22/2013
Kathy would recommend this product to a friend
Pump is quiet, my protien skimmer is louder. Easy to mount and assemble. All parts included. After 3 weeks, tank is not so clear, but phosphate level is lowering. The sponge in the carbon canister drops down, but according to BRS as long as the carbon stays up-no worries. Seems to work well so far. Don't like: I have to constantly adjust the flow into the GFO canister, not sure why, it is an inconvenience and slight worry.
Effectiveness, Ease of Use, and Esthetics By Austin on 3/22/2013
Austin would recommend this product to a friend
With so many attributes to look after in our tanks we in the reefing world look for 3 things: effectiveness, ease of use, and esthetics. The BRS GFO & Carbon Reactor gives us all three. This is the most integrated, cohesive, and effective unit to pull out unwanted phosphates and nutrients from your tank. Because the reactors are combined it makes the unit more efficient in processing water and reduces the number of pumps in your sump. The removable cartridges make this the easiest reactor to maintain. I've purchased an extra set just for added simplicity. Lastly, the space it takes up is minimal, especially if you compare it to other reactors required to do the same job. For added space management you can mount this reactor to any wall. I would absolutely recommend this reactor to anybody.
Pump could be better By Travis on 3/15/2013
Travis would recommend this product to a friend
I really like the combined chambers to save space however the MJ1200 pump just seems too weak. I have the unit almost level to not lose much head pressure and it just doesn't seem to push what I thought it would. I will be switching out the pump as soon as I can. My advise is to just buy the unit and get a different more powerful pump.

You are able to watch all media tumble and react with it. 100% effective
I am using BRS GFO and BRS Premium ROX 0.8 carbon in mine,ridiculously easy to change out media. Thanks BRS!

Needs to be modified By lostmyz on 2/28/2013
lostmyz wouldn't recommend this product to a friend
No offense, to everyone who likes this product. I initially bought it and thought it was great. However, after months of using the product I have to say it is sub-par. It is a glorified RO/DI canister with a removable chamber (which is cool for easy clean out). With that said, it is not very efficient. Due to the fact the flow stinks through it even with the MaxiJet 1200 attached. You constantly have to monitor it because it gets clogged and the flow slows down. Also a down side to this is the fact that te Chambers are connected in parallel. And the flow drastically declines in the Carbon Chamber after a while as the GFO chamber slows down. I think the product would be better engineered if it allowed you to have individual flow to both chambers and the ability to control said flow. All you need to do is rotate the Canisters on how they are attached to the mounting plate. Add a "Y" fitting with 2 valves one for each canister and than on the outflow side connect the outflow with another "Y" fitting and you are done. This will add a lot of control to the system and no account for as much clogging and decreased flow. It is just my two cents on the matter.
Great price but tricky to get the flow. By Isaac on 2/28/2013
Isaac would recommend this product to a friend
I will recommend this product to others because with a few tricks it works very well. I had many problems with trying to get the flow to stabilize. It would work well for a day and then the flow would just stop and everything would just settle to the bottom of the canister on the GFO side. It took a few tries before I realized that it was because tiny bits of GFO were passing from the GFO canister into the bottom of the carbon canister and blocking all of the water flow. What I found was that if I left the carbon canister out for a day and only ran GFO for the first day or first few days, all the small pieces of GFO would have passed through and I could add the carbon without fear of getting the bottom carbon sieve clogged. Also, the sponges don't hold their place very well at all.
