Highly controllable electronic propeller pump for reef aquariums Programmable wavemaker for custom aquarium water movement Recreate ocean currents in aquariums with enhanced wave modes Experience ocean-like currents you can control for exceptional aquarium water movement. EcoTech Marine VorTech EcoSmart Propeller Pumps take precision water movement to the next level. Upgraded EcoSmart Driver boasts improved wireless range (wireless-enabled models only), extra wave modes and more. Sleek driver design, easy-to-use controls, wave speed control dial and illuminated LED interface make custom precision flow settings effortless. Signature bracket-free VorTech propeller pump with magnetic coupling places the motor outside the aquarium. The result is the smallest in-tank footprint that delivers powerful yet gentle flow in multiple controllable modes for the ultimate reef experience. Advanced Application: When you use multiple wireless-enabled VorTech pumps (each sold separately), any EcoSmart driver is capable of operating either as a master or a slave pump. A master pump broadcasts a wireless signal and a slave pump receives this wireless signal. On any one aquarium, you can have up to six different master pumps broadcasting on unique frequencies. Each of these master pumps can be synced with an infinite number of slave pumps for endless flow possibilities.
