Not sure if this was asked yet but......
Since I don't always run carbon and having sit in the reactor and to be run every now and then , would be easier just to use let's say 5" RO housing with carbon and maybe 30 micron pre filter (if one at all) ? I'm sure getting carbon in bulk is probably cheaper but if you can filter thousands of water to make your RODI it should work too, specially if you but some can't of pre filter so it does not clog too fast
this is just a thought as I don't have too much room under my tank (waterbox 90.3) to run a lot of media reactors
