protein skimmer

A protein skimmer is a device used in aquariums, especially saltwater tanks, to remove organic substances and waste before they break down and pollute the water. It works by creating a column of foam or bubbles that attract and trap proteins, oils, and other impurities from the water’s surface. These impurities are collected in a cup for easy removal, helping to keep the water clean, clear, and healthy for aquatic life. Protein skimmers are essential tools for maintaining optimal water quality in marine and reef aquariums.
