these units are not only cost effective, the ease of maintance is the strong point... have an extra cartrige ready and changing your media is a 2 minute job... (Posted on 3/21/12)

I am a fan of BRS and their product lines. This is a high quality and easty to put to use product. All required parts supplied and many are pre assembled. Great Product (Posted on 3/8/12)

The supplied sponge filters keep GFO and granulated carbon in place. I wanted to try Purigen but it is too small for the sponges to hold. I wrapped the top/bottom sponges with bags I kept from some Chemi-Pure Elite I had used up and it works well by securing the bottom sponge with a couple of small zip ties that poke through the sponge so it wouldn't float up (the supplied bottom sponge was hot glue down). My recommendation is to fill no more than half with Purigen to allow the little balls to tumble by using a valve to get the flow just right.

I also installed a regular sized filter housing with a 180 micron filter post Jumbo BRS reactor to keep the reactor contents from entering my tank, in the event it leaks by the sponges.

The Jumbo BRS is built like a tank and should last a lifetime.

Bought one of these for GFO, it is pretty big and built very well. Very easy to get up and running. The only down fall is when using GFO it is hard to see when its tumbiling. Would be nice to see them update the cartridge to the new clear hard shell. (Posted on 2/20/12)

Purchased this for my 125 gallon tank to run Carbon. Easy to use, did not make a mess and no leaks. (Posted on 2/10/12)

This product was very well made and lives up to all standards. I fully recommend this product for the price. (Posted on 1/8/12)

Worst reactor I've ever tried. Screws that hold chamber to metal bracket strip easily. Sponges in reactor clog when using GFO. Sponges come unglued then fall on media not allowing media to "tumble" . (Posted on 11/10/11)

After few weeks of research I bought 2 Jumbo reactors for my 150G+50G Sump. One for GFO and second one for Carbon. Very solid construction. It's a excellent addition to my system. They are working perfect with Eheim 5000 Compact+ pump. Very easy maintenance.

The issues with the heat glue not sticking to the filter part where the cap is, it's NOT a problem. It's very easy to fix it.

I strongly recommend this product for 120G plus systems. (Posted on 10/5/11)

Currently am running full of carbon on my 180 . Setup was easy and am running this and the smaller reactor with gfo and circulating my chiller off of a mag 9.5. Another solid product from BRS... (Posted on 9/15/11)

I ordered 6 of these and 2 of the 6 had issues with the heat glue not sticking to the filter part where the cap is. Instructions online (Video) are not step by step so if you are a NOOB it does take a little understanding to figure it out exactly. (Posted on 8/12/11)
