Should have bought this sooner By Frank on 11/23/2013

I decided to purchase this dual reactor for my 180g reef tank because I was continuously having outbreaks of cyano and various types of algae. I tried several things to get it under control and most only appeared to work for a week or so. So far I have had the reactors set up for about 6 weeks and have not seen any reappearing algae.
*Also I am using the BRS high capacity GFO*
Great but... By Jake on 11/19/2013

I feel this is a great product, I've had it running for two weeks now with Phosban GFO and Marineland carbon. haven't seen any problem with the gfo loss of tumbling but do see a bunch of air bubbles in the carbon chamber and can't get them out. The chambers are sturdy and connect very well, but the hanging bracket is very weak and when i hung it on the wall it tilts, i had to put a towel behind it to keep the chambers in an upright level position
Maybe for a tank less than 100 gallons total By Nicholas on 11/7/2013

I've got a 120 gallon tank with a 40 gallon sump (take out live rock space, etc, and I end up with about 120 gallons total). Anyway, with that sized tank, it takes almost 2 cups (the maximum amount) of GFO and 1.5 cups of carbon (I am going to have to switch to the more expensive ROX just to drop the amount down).
Anyway, I bought it bundled with the recommended MJ1200 pump and the flow control is great... For about 2 days, then it is a matter of turning it up every day just to keep water flowing. Definitely NOT made to really handle that much media, at least with that pump.
Also, the carbon chamber won't stay filled with water. I was told by BRS that this is OK, but is sure doesn't seem like it. Even after purging the air, it takes about a day before it has a lot of air.
I am now running this dual reactor with nothing but the foam "pre-filters" in the carbon chamber just so that I can keep water moving through the GFO.
So I basically bought a dual reactor that can only be used as a single for my sized tank. Either that, or I toss out the $30 MJ1200 and get something bigger.
I feel mislead by their product information.
Love it By Anchor10 on 10/25/2013

Everyone should have one of these for their reef tank. I had runaway phosphate trouble and saw a difference in 24 hours. So easy to use and I like that I can hang it as opposed to setting it on the floor.
Clumping By Mark on 10/21/2013
Mark would recommend this product to a friend
Decent quality product, but I find with BRS standard GFO I must use much more flow than described in the instructions to avoid the GFO clumping together. And as another poster mentioned, it is critical the reactor is level as well. The question now is if the extra flow will result in more fines or short GFO life?

Mounting bracket could be a bit stronger...over time there could be issues. Breakage

Diatoms Still Blooming By Jerry on 9/28/2013

Dual reactor installed easily and seems to work as advertised by keeping phosphate low. However, Diatoms must be thriving on silicates introduced from I haven't discover where.
Worth every penny! By Stephen on 9/27/2013

I absolutely love this reactor! Took about 5 minutes to install. I attached a Maxijet 600 and it works great. If you need a reactor get this one.

Best thing since sliced bread. My Phosphate levels have drastically gone down. One of the best purchases made for a great value.
Simple By John on 9/13/2013

Simple easy to use and works great ! Does not require much in the way of a pump to churn up the gfo ! Really no algae in my tank at all , but also no coraline algae ! Used this from the start, change out gfo once a month and carbon every 2 weeks !
