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 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 Bak Pak Dual Features at a Glance:

• Mechanical filtration for saltwater and mini-reef aquariums.

Made of high impact plastic for years of dependable use, even under the adverse conditions of a saltwater environment Ideal primary filter for saltwater aquariums. Skilter 250 pumps up to 250GPH and will handle 10-55 gallons. Skilter 400 pumps up to 400 GPH and will handle 30-100 gallon aquariums. The protein portion of either system will handle aquariums up to 125 gallons, provided adequate mechanical filtration is present. Quiet, dependable power unit employs only one moving part to assure virtually trouble-free operations. Uses disposable filter cartridges and activated carbon.

Bio Matrix Cartridge

Protein Skimmer

Vortex Reaction Chamber is much more efficient than air-driven protein skimmers. It creates a powerful whirling, swirling column of air and water that rapidly draws dissolved wastes (protein-laden bubbles) upward through the column and into the high-capacity Collection Chamber, where they burst to form a frothy solution. This solution of unhealthful dissolved organic compounds is contained there, where it is kept separate from clean water until it can be removed. The large capacity cup holds more and needs emptying less often.

Adjustable water flow and air injection rate for precise performance.

SeaClone Protein Skimmer Features:
• Includes powerful Maxi Jet 1200 pump.
• Functions as external "hang-on-tank" skimmer or sump skimmer.
• Requires no air stones
• Saltwater tanks

Customer comment: This is a great little protein skimmer - especially for the price. If it springs a leak, it is almost always an O ring. Because it is a less expensive model, the O rings need to be reseated a little more often.

Completely assembled. Ready to go right out of the box.

Marineland In-Sump Skimmer Features:
• Includes powerful Maxi Jet sump pump.
• Needle wheel impeller contained in the base eliminates the need for external pumps and hoses.

The Protein Skimmer is driven by a rejuvenation venturi powerhead. Bubble dwell time is increased by the counter-current flow in the skimmer column. The quality of the foam collected can be controlled by raising and lowering the collection cup.

To set up the BAK-PAK™ 2, hang the unit behind the aquarium and plug it in -- that's it. New improved design incorporates an easy to clean intake tube and an enclosed, directional outflow to reduce salt splash and micro-bubbles entering into tank. The new design also uses a smoke colored break-resistant collection cup.

The new Accela pump is similar to the Maxi-jet 1200, however, it includes some important added benefits. The pump has been modified to include a venturi intake which efficiently draws in more air with less restriction on the pump. This results in more effective protein skimming with a significantly increased "sweet spot" for skimmer operation.

CPR Accela Pump Features at a Glance:
• Increased air to water ratio
• Less restriction on the pump results in longer pump life
• Modest power consumption- 20% less than the Maxi-jet 1200
• UL listed with a 6 ft. grounded plug

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.

CPR Bak Pak 2R Features at a Glance:
• 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 an additional BAK-PAK.

Needle-wheel skimmers are the most efficient of all skimmers for removing dissolved proteins.

The Super Skimmer is a high-performance foam fractionator with aspirating venturi. This mixture allows the needle wheel to divide the fine bubbles into a dense froth which is injected into the reaction chamber. The deposited air bubbles and water mix together in a spiraling vortex inside the reaction chamber to increase both contact time and deficiency. As the bubbles rise, their surface areas attract and collect fine proteins and organic compounds before they break down in the water and are then deposited into the collection cup. The efficient removal of highly-concentrated waste products results in a better environment for the aquarium.

Super Skimmer - Needle-Wheel System Features:
• Dual application system: hang-on tank mount or sump hook-up installation
• Pump included with patented needle-wheel system and aspirating venturi and equipped
• Versatile water-level dial adjustment dial to easily stabilize water flow within the reaction chamber and gives outstanding control of foam consistency.
• High-grade acrylic construction with easy-twist collection cup for quick and effortless cleaning
• Bubble-production diffuser filters and prevents the flow of micro-bubbles from the protein skimmer into the aquarium
• 125 gal. & 220 gal. units have easy-twist collection cup with drain line for easy cleaning.
• Ideal for Reef and Saltwater Aquariums
• One Year Limited Warranty
