I have a biopellet reactor running on mine. I need to upgrade the pump, because from what I've read you need a moderately strong flow though the pump to keep them tumbling. They should tumble more than what you would expect to see with a GFO reactor. I'm running a TLF reactor with the bioplastics conversion kit (which, let's face it, consists of a couple plastic stitching rounds from Michael's for thrice the price).
