Protein skimmers are the heart of marine water aquarium filtration. That is permanently released into the water by microorganisms, invertebrates, and fish. The powerful and economic skimmers remove particles and floating matter, and they aerate the aquarium.
A protein skimmer or foam fractionator is a device used to remove organic compounds such as food and waste particles from water. It is most commonly used in commercial applications like municipal water treatment facilities and public aquariums. Smaller protein skimmers are also used for the filtration of home saltwater aquariums.
