Protein skimmers are used mostly in saltwater aquaria to remove organic compounds from the water before they break down into nitrogenous waste. Protein skimming is the only form of filtration that physically removes organic compounds before they begin to decompose, lightening the load on the biological filter and improving the water’s redox potential.

 Protein skimmers extract dissolved organic waste products (proteins) from the aquarium by mechanically removing them through foam fractionation. Efficient skimmers remove proteins before they breakdown and pollute the water. Skimming enhances the quality of the aquarium’s environment as well as its appearance.
