BAK PAK BIO-FILTER
By CPR Aquatics

Cyclone BAK-PAK™ 2 Bio-Filter

The Cyclone 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, but multiple units may be used for larger aquariums. Water first enters the Protein Skimmer column from the aquarium. It 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.

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.
