Hey Roger,
Thanks for your reply. I just received my 6000 w/ a single controller. I positioned it exactly the way you suggested. However, my single controller seems not to be working properly. The lights for Pulse one and two flicker on and off and the pump on light is on, but when plugged into the stream pump, the pump stops working. When I unplug the controller, the pump turns on with no problem. Any idea why this is happening?
