The Vevor aquarium wave maker is a compact circulation pump designed to simulate natural ocean currents for freshwater and saltwater tanks. It delivers up to 3963 GPH while using 40W of power and includes a controller for adjusting wave frequency and flow rate. Three wave modes, plus feed and night modes, help create a more natural and comfortable environment for fish and corals. A strong magnetic base and 360° rotating pump head allow flexible positioning inside the tank. Its pure copper motor and ceramic shaft support quiet, durable performance.
