Lights on at night vs. Day

[phi delt reefer]

My city just started using smart meters and the cheapest time to use electricity will be at night after 7pm.

I was wondering if there would be any impact to the tank during the day for the room the tank is in won't get pitch black during the day but it's not sunny either. I am only home in the evenings so it would be nice to see it all lite up when i am home. Also the tanks temp would probably be more stable for it's cooler at night and my lights can raise the water temp 3 degrees when all 8 bulbs are running.


Tank will have sps but right now has clowns, cardinals, wrasse, tailspot, chromis and some different shrimp, anemone, favia and some zoos.

Thanks
