The Dymax Vortex Fan is an effective way to lower the water temperature in an aquarium, especially during the warmer months of the year. This easy-to-use fan has a built-in clamp, allowing you to securely attach it to the edges of most aquariums. By blowing air across the water's surface, the fan helps reduce the temperature through evaporative cooling. And thanks to its flexible arm, you can easily adjust the airflow for optimal performance. The Dymax Vortex Fan is available in the W-5 and W-8 sizes.
