6ft tank - two MP40s left & right- tip/tricks on getting a WAVE back n forth (?)

[ZoWhat]

6ft tank

Two MP40s, one left & one right walls

I do know to create a WAVE you only pulse from one side (I think) while the opposite side is 0% flow

Need tip/tricks on getting a WAVE back n forth

...as far as Intensity-Flow% and Pulse-Timing in seconds
