Fluval Sea CP2 Circulation Pump is a versatile water mover that creates beneficial currents in saltwater or freshwater aquariums. With a mid-range flow output, the CP2 helps distribute nutrients and oxygen evenly while simulating natural water movement that fish and corals thrive in. It has a compact, magnet-mounted design and operates quietly and efficiently. By eliminating stagnant areas, the CP2 contributes to healthier water conditions and more active, well-oxygenated tank life.
