This moving bed reactor is the 3rd aquarium filter or pond filter model of this video:

In the previous video, I use box container, but in this video, I use tube container and put the pump that way to make the water flow in circular motion. I don't know if it has impact on the filtration capacity, but I'm sure that this model use less electricity because even without airstones, the K1 media movement is good already.
