So right now I have a reactor and I am running gfo. I was going to get a BRS dual reactor and had planned on running carbon and bio pellets. Correct me if I'm wrong but carbon does not tumble, what about bio pellets, do they need to tumble? What would you all run if you had three reactors? Should I just get two more of the phosban 150s or would I be ok with the dual from brs?
