CPR Aquatics Bak-Pak Hang On Protein Skimmer

Dimensions: 7 1/2 Inches Wide 3 Inches Deep 17 Inches High

The BAK-PAK™2 Bio-Filter is the second generation external, hang on the back, combination Protein Skimmer and Biological Filtration unit from CPR. The BAK-PAK™ 2, like the original, is designed for tank sizes up to 60 gallons. Water first enters the Protein Skimmer column from the aquarium and then flows through the biological chamber filled with Bio-Bale™ filtration media before returning to the aquarium.

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.

Protein skimmer and biological filter in one

• Hang-on design installs in seconds. Simply attach the included powerhead and plug it in.
• Utilizes new Acella pump with high output rejuvenation venturi system.
• Accela pump provides increased air to water ratio with less restriction on the motor: resulting in longer life.
• Hand-crafted with the highest quality acrylic.
• Adjustable, impact resistant collection cup
• Recommended for aquariums up to 60 gallons

* Upgrade to a Taam Rio 600RV

These powerheads feature the Rejuvenating Venturi design. By drawing the air directly into the impeller, it is able to create a much stronger suction for air: which works great for drawing air out of overflow boxes (such as the CPR overflow boxes). The air is then chopped up by the impeller: which creates ideal bubble sizes for protein skimmers.
