New pool, chlorine with ozone.
The guy who did the startup set it up to run overnight, 10pm to 6am.
The guy at the pool store (same company as the builder) said that since I have ozone, it's best to run it during the day (sunlight) because that's when the ozone will be the most effective (based on the fact that the ozone does nothing when the pump is not running, of course). He recommended 10am to 6pm.
My electricity cost is not variable, it's the same rate regardless of the time of day.
Running it during the day makes sense to me - any reason that's a bad idea?
