I installed my wavebox tonight... all I can say is WOW! The box generates the back and forth motion throughout the tank. It reminds me of shallow dives at Bonaire with the gorgonians swaying gently back and forth. I also am running 4 Tunze 6100 Streams independently from the Wavebox. The Streams run in pairs, one pair on the left of the tank and the other on the right. With the wavebox there is a huge improvement in water flow. ALL of the water moves as a wave across the tank that produces an alternating current that is the ideal high vloume, low velocity. This tends to suspend detritus and other waste which is then hit by the Streams and pushed towards one of the two overflows that are located on opposite sides of the tank. Now that I see the swaying motion of my anemones and several LPS corals, it's as if something was missing before the box was installed.....truly worth every penny!
