A protein skimmer is a device used in aquariums, particularly saltwater tanks, to remove organic compounds from the water. It works by creating bubbles that attract and trap proteins and other waste materials, which are then collected in a separate chamber. This helps maintain water quality and supports the health of aquatic life. Protein skimmers are essential for reef aquariums, where delicate species like coral and fish thrive. By reducing harmful substances, they contribute to a stable environment, making it easier for hobbyists to manage their tanks effectively. Regular maintenance of the skimmer ensures optimal performance and cleaner water.
