i have two XFR330 and i want to creating a rocking wave motion in tank as exists on natural reefs.
I understand you have a async mode where the two pumps work oppposit of each other , wouldnt this create such a flow pattern ?
as i one pump will be ramping up and other ramping down .
I am not understanding how the alternating gyre setup (which requires additional purchase of hardware) is any different from the async mode.
