A protein skimmer is a device that extracts protein and other organic matter from water.

Protein skimmers work on the principle that complex molecules are caught in small bubbles. Therefore, in skimmers powered only by air, a lime-wood airstone is used because they provide the finest bubble stream.

The bubbles are released into a submerged tube, which is topped with a Venturi valve. This helps the smaller bubbles flow out of the top of the valve more easily.

The venturi valve is surrounded by a cup, so when the small bubbles overflow the Venturi valve, they fall into the cup. There, the bubbles degrade and the organic waste matter is left.
