I bought the NextReef MR-1 Monster around 2 years ago and have had time to get a well informed opinion of the reactors.
The MR1 Monster features dual 21" chambers and holds up to 2 gallons of media.
Recommended Tank Size: 600 gallons Marine / 1200 gallons Freshwater
Height: 23" Overall Height / 21" Reaction Chambers (585mm / 535mm)
Footprint: 12.5" x 6" (325mm x 150mm)
Reaction Chamber: 21" x 4" (Dual) (535mm x 100mm)
Total Capacity: 465 cubic inches / 2.0 gallons / 255 fluid ounces / 7.6 litre
Inlet / Outlet: 1/2" 90 Degree Barb Fittings - fits standard 1/2" ID tubing
Initial impression was nice build quality and holy cow were they big capacity wise. Made the 1lb of carbon look like a joke!
Assembly was easy; screw in the supplied barb fittings (teflon taped from the factory iirc) slap on the tubing/the pump, fill the chambers, close the lids and plug in the pump. Up and running in around 20 minutes.
When assembling and filling the reactors a couple of things were noted.
1. You need something to push the sponge down, just like the TLF Phosban reactors.
2. If you pick up a cheap pvc cap it will make filling the reactors as easy as just dumping in the media. As with the TLF Phosban you need a finger or tape to cover the feed tube, but this is just not quite as polished of a solution.
Pretty standard things.
When I moved these over to the 240g I changed the fittings over to 1/2" PVC and hard plumbed with unions.
Flow is now controlled to each reactor on it's own and this makes dialing them in to the perfect flow rate easier.
As this is a dual reactors setup as one piece media is easiest to change at the same time. It does not have to be, but you will end up draining both chambers unless you place valves on the lids.
This is not a big deal as I replace carbon and phosban at the same time.
Overall very happy with them
