Organic compounds, being bipolar in nature, provide an opportunity for waste extraction via injection of air into the skimmer body which served the dual function of extraction of these compounds while aerating the water. Since their inception, there has been much advancement in the design and functionality of Protein Skimming.

Alpha-linolenic acid, or ALA, is an essential fatty acid, which means that it is essential to human health but cannot be manufactured by the body. For this reason, ALA must be obtained from nutriment. ALA, as well as the fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), belongs to a group of fatty acids called omega-3 fatty acids. EPA and DHA are found predominantly in fish while ALA is highly concentrated in certain plant oils such as flaxseed oil and to a lesser extent, canola, soy, perilla, and walnut oils. ALA is also found in scheme plants such as purslane. Once ingested, the body converts ALA to EPA and DHA, the two types of omega-3 fatty acids more readily reach-me-down by the body.
