All skimmers have key features in common: water flows through a chamber and is brought into contact with a column of fine bubbles. The bubbles collect proteins and other substances and carry them to the top of the device where the foam, but not the water, collects in a cup. Here the foam condenses to a liquid, which can be easily removed from the system. The material that collects in the cup can range from pale greenish-yellow, watery liquid to a thick black tar.Protein skimming removes certain organic compounds, including proteins
and amino acids
, by using the polarity
of the protein itself. Due to their intrinsic charge, water-borne proteins are either repelled or attracted by the air/water interface and these molecules can be described as hydrophobic
(such as fats or oils) or hydrophilic
(such as salt, sugar, ammonia, most amino acids, and most inorganic compounds).
protein skimmers are designed mainly for molecules,I never said they wern't used to remove detritus but the best way to remove it from LR
