"Time of Use" and the art of war!!!

For my pool I use two products that help reduce algae, chlorine use, maintenace effort and pool pumping time.

1) NoPhos or now called PHOSfree to reduce phosphates needed for algae to grow. If your phosphates are more than 100 ppm it is much easier for algae to grow

And

2) Zodiac Nature2 express cartridge that slowly reduces mineral sanitizers. They recommend changing the cartridge every six month, but in San Diego I just use it for the summer time. (Reminds me I have to order for this summer. I bought the starter kit at Leslie's Pool Supplies, normally order the replacement cartridges over the Internet as it is much cheaper.)

I usually split my pump time - a few hours at the end of the day and a few hours at beginning of the day to mix and distribute the hot/cold water water at the top (covered with solar blanket). I also cover the pool pump filter with an umbrella so the water in the filter doesn't get extremely hot in the summer.

Good luck with your energy savings.
