It is hard on the holder hardware but it should take it, if it broke it was likely a defect. The 7095 can pulse as fast as 1 second, the 6091 is as fast .3 seconds, on a very long tank 10 ft or more the multicontroller could likely make a wave. The new 7096 will be able to run wave functions. The box does serve to boost the efficiency so it may take 2 or more non wavebox streams to get the effect of a single wavebox. Any surge device stresses the seams of the aquarium and will shorten the tanks life.
