The Professional Recirculating BioChurn reactors are for those that demand the ultimate control over your Biopellets solid carbon dosing. The superior “Power Churn” design easily fluidizes large amounts of biopellet media without blasting it with outrageous flow just to fluidize the media which is a common downfall to other available biopellet reactors on the market today. The unique motion these innovative reactors produce allow for much greater suspension of the media in a cyclone "churn" style motion created with their patent pending churn plate.  Equipped with the quality Aquatrance recirculation pumps and features independent flow valves so the user can independently control the flow of media within the reactor. 

The BioChurn Reactors come in Four Series including the in-sump, External/Recirculating and the Commercial line. For the ultimate control of PO4 & NO3 look no further than the BioChurn.
