Reactors include 2 types of filter pads for different media types, tubing, valve and input-side barb union connection.  The output fitting is a vertical barb fitting.  Both fittings are 1/2" NPT, threaded into the lid.

The MR5 ships standard with a pair of Mesh Disks, which makes this reactor an excellent choice for fluidizing larger chunk carbon.  The mesh disks don't clog and are the correct size to keep larger size carbon contained. If you're using ROX 0.8, then you'll want to use the foam pads that also ship with the reactor.

For Biopellet use, we recommend our optional Biopellet Nozzle which provides excellent pellet movement and no clogging.  This nozzle replaces the bottom media plate and mesh disk.  We recommend keeping the top screen in place to prevent floaters from escaping.
