Even though GHL has released the ProFilux III system already, you might be one of the thousands of owners of a ProFilux II or Profilux II ex system. Thankfully you’ll be able to upgrade your unit from a II to a ProFilux III. We are not aware of any other aquarium controllers to offer this mostly equipment upgrade, which makes this very unique within the industry. Also we received word that plus II owners will be able to upgrade to the ProFilux III model for only $198 until the end of October. Check down below for the additional pictures of the upgrade unit.
