Fluidized Media Reactor

31 reviews
$ 94.99
Our fluidized media reactor is designed to efficiently filter water with a variety of media types. The reactor includes 2 types of filter pads for retaining different media types such as activated carbon or granular ferric oxide (GFO).  The included mesh disks make this reactor an excellent choice for fluidizing larger grained carbon.  The mesh disks don't clog and are the correct size to keep larger size carbon and some GFO types contained above the disk.  If you're using very fine grained media such as ROX 0.8 carbon, then you'll want to use the foam pads that also ship with the reactor, or a mesh bag.  Also included is a flow control valve, 5 feet of soft tubing for pump attachment, and barbed union disconnect fittings.  The MR5, our small sized reactor, only has room for one union connection; the output fitting is a vertical barb fitting.  In all sizes, both barbed fittings are 1/2" NPT, threaded into the lid.

Unsmooth Surfaces

I bought the mr10 and mr16 reactors and I was not satisfied with them. Both items has unsmooth top cover and base and others. Sure, these would not affect the item’s performance. But given the fact that I bought them brandnew, I was not expecting these spots of bother. Just my two cents.
