I'm not an expert but if it were my pond I would try midnight to 6am for a couple days then go swimming late afternoon. You likely will have some stratification but if the lower water seems extremely cold you need to increase the time. That would be my non_approved redneck way of approaching it.

One hp seems like about twice as much needed for that size pond.

Night is when algae are not producing DO via photosynthisis so I would run it at night to help water take on DO via the air water interface at the surface.
