Dont waste your money. By agspin on 8/23/13

I really like the products Reef Octopus puts out so I decided to upgrade my biopellet reactor to the biochurn after watching the video of it in action. In concept it seemed great and the video shows the pellets really being churned. I set it up and and ran it with the provided pellets and it ran great. Since they only provided 500ml of pellets I decided to add some of the ones that I had in the old reactor. Thats where the nightmare began. The old pellets are naturally smaller but still have at least 50% life left. Apparently thats too small because they get wedged between the rotating bottom plate and the cylinder wall which causes it to a stop rotating. Naturally without any motion the pellets will eventually clump together. This is a maintenance nightmare. You will have to constantly check to make sure the plate is moving and then replace the pellets when there is still half the life left in them or they will jam the spinning plate. What a waste of $400. I'm going back to my old unit and getting rid of this one.
