Do you see any media in the picture?
There is no media in the reactor. Media in the reactor slows down flow rate. Also it can clog the reactor. I have had this happen before. I took the media out of all my reactors and they work just fine.
I have never built a shorter reactor. I have no doubt they would work just as well.
