CPR has taken the proven technology behind the Bak-Pak 2, and created the NEW Bak-Pak Dual Pak. The Dual Pak provides a complete hang-on filtration unit for tanks up to 100 gallons that incorporates two protein skimmers with a biological filtration chamber in the middle.

Using proven Rio Rejuvenation Venturi technology, the protein skimmers are flooded with bubbles for constant removal of excess organics. The biological chamber utilizes CPR's Bio-Bale biological filter media to provide maximum surface area for beneficial bacteria to colonize.

Simply hang on Bak-Pak Dual Pak on the back of an aquarium, plug in the rejuvenation venturi powerheads, and enjoy a worry-free operation!

CPR is proud to introduce the hang-on skimmer that all reefkeepers have been waiting for, the Cyclone Bak-Pak 2R. This new skimmer is designed for use on reef tanks where biological filtration is not necessary, but still incorporates all of the other features that have made the Bak-Pak line of skimmers so popular.

New "Tri Chamber" design of the Bak-Pak 2R takes the place of the biological section, and when combined with a new and improved outlet design, provides an effective way to reduce bubbles caused by system imbalances.

• Incorporates CPR's proven high performance rejuvenation protein skimmer.  
• No need to purchase an overflow or return pump, the Bak-Pak 2R simply hangs on the back of your tank.  
• Use on tanks utilizing the Berlin or Jaubert Method, where supplemental biological filtration is not desired.  
• Easy to setup, easy to use, easy to clean.  
• For tanks up to 60 gallons. For larger tanks use additional Bak-Paks.
