The JBJ Ocean Pulse Duo is an innovative wavemaker that is specifically designed to replicate the natural alternating rhythms of tides and currents for home aquariums. The wavemaker instantly creates turbulent flow patterns with adjustable cycle times from 10 seconds to 6 minutes. This water movement is vital for the success of invertebrates, animals with symbiotic algae, filter feeders, and fish. The natural currents in the ocean bring randon flow and wave cycle patterns that provide nourishment while suspending waste particles for filters to effectively trap.
