Time of day (demand based) electricity rates will be introduced to my area soon. The rates are about 3 times higher during the daytime weekdays compared to weekends and late evenings.

I have traditionally operated my chlorine generator (Aquarite) and pump (1hp) for my inground pool (18'x36') with pressure side cleaner (Polaris 360) successfully on a timer for about 16 hours per day during the daytime (7am to 11pm). I religiously use a solar blanket, so I don't need to use my heater. It has been extremely easy to maintain and manage.

Obviuosly I want to minimize my bills, but I know that the chlorine is used up the most in the sunlight and heat of the day. I want to change the scheduling for the pump and chlorine generator to operate mainly at night and weekends.

Some issues I may have without circulation during the day:
1) exagerrated temperature gradient with solar cover - hot on top and cooler below
2) inefficient passive heating with solar blanket without circulation
3) potentially more visible debris and dirt when pool is in use without active skimmer
4) noisier pool and shed with pump operating all night - may upset neighbours
5) chlorine levels dropping below acceptable in sunlight and heat

Should I bump up the chlorine level in anticipation that it will be depleted during the day? Are there any other pitfalls I should watch out for when I try it out this coming season? Has anyone tried this strategy to run the pool off-peak hours successfully?

Should I take a more conservative approach and operate at intervals during the day and night. ie 2 hours on 2 hours off. What scheduling strategies have worked for others?

Your experience and knowledge is appreciated.
