I have no idea how to plumb it? How do I get pond water to it, and then back
to the pond on a slow cycle?

Use two different water levels and pump from the lower to the higher
water level and make a spillway or overflow pipe for water to gravity
flow back to the lower water level. You can determine the amount of
water movement by the pump size.

Actually that will work with one water level if the two ponds are
connected by a return pipe that stays full of water.
