Tim from Ecotech responded to my issues in their forum:
When viewing the tank from the back, try rotating the drivers 90deg's clockwise for the ones on the left side, and 90deg's counter clockwise for the ones on the right side. This will orient them so that the antenna's are pointing right at one another, and should take care of any range issues. Alternatively, it does look like you have enough cord to perhaps move them each about one foot closer; that could help too.
As for the gyre flow, to achieve this you don't necessarily need them to be sync'd with one another, all that you really need are two timers. Looking at the tank from the left side panel, I would place one pump in the top right region, and one pump in the lower left. I would then set the pumps up opposite this on the other side of the tank, so that each pair in the gyre occupies either the top region or the lower region; I would not split a pair up between top and bottom in an effort to achieve the ideal circular flow for a gyre system.
Put each pair in green, constant speed mode, and set them up on a timer to come on for 15 minutes and off for 15 minutes while the other pair is off and on. There is no real advantage to having a master/slave group for this type of a setup, but you could do it with each pair. The only advantage that assigning them as master/slaves would provide is that you would only have to control the master pump's potentiometer, not both.
