n marine aquariums, the protein skimmer, also known as a foam fractionator or skimmer, is an important component of the filtration system. It is used to remove organic impurities such as proteins, fats, and other organic substances from the water. The protein skimmer operates on the principle of adsorption, where organic substances adhere to air bubbles and are then collected as foam at the water surface. The foam is then collected and removed in a collection cup to eliminate the impurities from the aquarium water.
