Great reactor, too small pump By Paul on 11/14/13

This reactor works great at tumbling bio pellets, but the pump provided is way underpowered to move the pellets for the size of the reactor. I had a spare Rio pump that's one or two steps up from the one included and with it, the pellets are moving and rotating the way they should be. Also, the pump included sounded like it was grinding rocks at the same time. Other than the pump, it's the perfect low cost media reactor that's small, uses very little power, and doesn't cost a fortune.
