Counter Current Protein Skimmers help prevent toxic tank syndrome by removing
proteins and other organics before they turn into nitrogen compounds or other
toxins that may be harmful to aquarium inhabitants. Through
ADSORPTION, protein and
other organic compounds in the water form a coating around bubbles as they rise
to the top. The resulting foam floods over the top of the foam riser tube and
is captured in the collection cup before it can re-enter the aquarium. Easily
adjusted, low maintenance protein skimmers come pre-assembled, with 2-way
plastic valves and hanger included.

Advantages of
Counter-Current:
Better Water Flow, More Effective Mixing, and Longer Contact Time
Water enters at the top of the skimmer and is drawn downward, using the full
length and diameter of the Contact Chamber. When the bubbles produced by the
air diffuser travel upward against the downward water flow, a spiraling
turbulence is created. The turbulence causes air bubbles and water to mix for
an extended period of time. This allows organics to be extracted more
efficiently. Contact time is also increased by using the tallest Protein
Skimmer that your aquarium will accommodate.
