When to run the filter.

The sun doesn't cause algae--improper chlorination of your pool causes algae. In the presence of too-low chlorine, the sun just provides the heat to speed growth up. As long as your water is properly chlorinated, you don't HAVE to run your pump during the middle of the day.

I run mine via a timer durring the hottest times of the day to help prevent alge growth. Circulating water is harder to grow alge then standing water.

Plus I keep the solor cover on during the day and circulating the water at the hottest times of the day helps keep the pool warmer.
Just my 2 cents.
