My electrical rates are lower from 9pm to 9am and I'm currently running my pump for 6 hours a day .
Is it better to run the pump in the evening from 9pm to 3am or in the monring from 2am to 9am. Since I have a SWCG my though was to run it as late as possible into the moring so it starts the day with a good dose of chlorine. would it be better to get chlorine back into is asap after the sun has cooked it off ?

or buy some more tippers for my timer and split it into 9pm to 12am and then again from 6am to 9am ??? ohh the options are unlimited I guess.

opinions?
