Skimmers for aquariums

Skimmers

— skimmers are used to remove bacterial film from the surface of water; they also effectively remove organic contaminants. Such films are formed due to food residues, oil, fish secretions and other organic substances. Skimmers are often used in saltwater aquariums, and in some cases they are also used in freshwater tanks where there are problems with film and contamination of the water surface. Note that skimmers are an auxiliary element of filtration and are used in conjunction with other aquarium filters.
