Bruce,
That's exactly what I want to do. Place one powerhead on one side and the second on the other. They will be plumbed so that the outflow comes from the front bottom corners of the tank.
Thanks for letting me know that the redsea pro doesn't really have a soft start. That's is the only reason I would get it. But how can they advertise that it does if it doesn't???
There are variable timer kits that will do the trick..

All you need here is a cheapo 9/12v powersupply (adaptor), DTDP relay and a nice little box.
