I have a Reef Dynamics BP reactor for 135 gallon system for sale. It was used 6 months. I finally gave up on BPs even though many have had success. Reactor is in very good condition. IMO it is a very well built recirculating reactor and has a unique valve to control the effluent, which is important when running BPs. This retails for $299 on Reef Dynamics' website. Asking $220 shipped in the US. PM me if interested.
