I've had my system off, and I'm about to do a new startup following the 15 min/double/double/etc rule.

Is there a particular time of the day that it would be better or worse to run the pump during my startup sequence? My schedule is pretty open right now, so I have the flexibility to do it whenever I want if it will make a difference one way or the other.

I've got about one surface-acre of water at the moment with max depths of 7-10 feet. There are two diffusers in the areas that currently have water. It's been quite hot here for a few weeks now. The pond is a year old with very little vegetation (other than good old slime).
