I have for sale a mint/clean condition but older model Vertex RX6 calcium reactor with Greenleaf Pro Co2 regulator and a 20 lbs Co2 tank for $400. I am located in East Brunswick NJ and can meet up locally or in Aquatic Obsessions. The reactor was used briefly on my system as sulfur reactor and I took it offline after few weeks usage. I do not have the tubes but you can get them from HD or Lowes easily. Please PM me if you are interested. This reactor although old has many unique features which you can learn here from the BRS video:https://youtu.be/O9EsW_NywW4
