Water movement is vital for the success of invertebrates, animals with symbiotic algae, filter feeders, and fish. The natural currents in the ocean bring random flow and wave cycle patterns that provide nourishment while suspending waste particles for filters to effectively trap. This innovative wavemaker is specifically designed to replicate the natural alternating rhythms of tides and currents in home aquariums. It instantly creates turbulent flow patterns with adjustable alternating cycling times from 10 seconds to 6 minutes. Equipped with an adjustable dial for quick and easy setup for virtually all types of invertebrates, corals, filter feeders, and fish that will gain immediate benefits. These benefits include: oxygen rich water for the entire aquarium, more stable water temperature, creates desirable turbulent flow patterns, flushes dead spots of detritus and accumulated waste, increases fish activity, and stimulates coral and invertebrate growth. Always research specific flow requirements for individual animals before making adjustments. Controls 2 pumps.
