SCWD wavermaker alternating current return

SCWD

SCWD is a water switching or current generating device. SCWD switches or alternates water in two or more directions, depending on set up. It is an excellent water current generator for both salt water and fresh water environments, whether tank or pond. The patent-pending device, which requires no electricity, directs water between two outlet ports at varying intervals. The higher the volume of water flowing through the SCWD, the faster the switching response.
