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!
