Protein Skimmers for Dummies - A simple explanation of how skimmers work

By Stan & Debbie Hauter, About.com Guides

The air driven counter current Lee's Skimmer operates much like the updraft in a Under Gravel Filter, using rising bubble in a tube to move water upward. Small bubbles, generated by an airstone at the bottom of the skimmer, rise to the surface. Larger bubbles are injected into a small tube in the skimmer body drawing water from the bottom of the skimmer upward and back into the tank or sump. This causes a downward (counter) current. This is an example of one of the earliest counter current skimmers.
