Protein Skimming can sound complex, but in practice it is actually quite simple. In most protein skimmers, small air bubbles are produced using venturi valve which mixes air and water in a special nozzle that produces a constant flow of fine bubbles. These bubbles float upwards, usually working their way through moderate current of downward moving aquarium water. Surface active molecules (proteins, lipids, and other dissolved compounds in the water) collect on the bubbles and are carried to the surface of the water column in the skimmer.
Over time, foam collects at the top of this column, which narrows into a smaller tube or an inverted funnel to further concentrate the foam. This foam will climb op over the edge of the tube of funnel and collect in skimmate collection cup from which it can be removed. The efficiency of the protein skimmer is determined not only by the amount of skimmate removed but also the skimmate density. In a well functioning protein skimmer, the skimmate can be the color of thick black coffee, with strong sulfus odor.
