To generate a wave, the best bet is the 6206 Nano Wavebox, you will get the biggest wave this way and it will cost less than 2 6055 and a 7092 which would be the other route. Keep in mind a wave lacks direction and in most cases is not sufficient as a sole source of flow, I would pair it with 2 6045's alternated at hourly intervals on a time or a single 6055 pulsed on a second 7092 controller, alternatively on a 7096 you could run the wavebox in wave mode and pulse the 6055. The 6206 will include a 7092 but it can only run one function at a time, either pulse or wave mode.
