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 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

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 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

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.
User error... By Sunny on 2/17/2013
Sunny would recommend this product to a friend
I need to apologize about my recent negative post... I dosed Ca and Alk at the same time in my sump with the BRS 1.1 ml doser and also placed the 1200 pump forthe reactor in the same area and it caused the strainer plates to clog (as well as the pump itself) which severely restricted the flow. Once I realized what happened I started dosing separately and place the return pump for my reactor in another area of my sump and actually had to gate the flow down some.
Phosphates beware By JPRO on 2/16/2013

I originally saw this product on youtube with both canisters containing GFO in the bottom and one with packed carbon at the top. With a 130 gallon tank this setup is working great with the pump supplied in the kit. The see through containers allow you to view the slow "boil" of the gfo.
Clogs and is useless after a week... By sunny on 2/14/2013

I have the single and it works great, this one is a waste of money. It would be nice for BRS to address this issue and get it resolved, the pump that came with this unit does not have enough flow and they should sell one that is designed to work for longer than a week.

I used to use filter pads and place it in the water flow. Worked but not that great. So I bought the dual reactor and let me tell you that this is the only way to go. You are able to watch all media tumble and react with it. 100% effective. Saw great results immediately. Another quality product from BRS..
Great for the budget minded reefer! By JABlacher on 2/3/2013

Can't argue with this setup at all. A twin canister reactor that you can mount on the wall with the attached mounting plate, a ball valve to adjust the flow and the available pump. How could you possibly get a more complete product at a better price. Put your carbon in one and GFO in the other and your media nightmares are over. This reactor is built like a tank and is ridiculously easy to change out media. Thanks BRS!
