Apples and oranges.

Michael is talking about circulation when the water is most at risk, and, with an SWG, all is different.

Adding chlorine after the sun sets allows the chlorine to fight the algae without risk of it being broken down too soon by UV light.

As for your pool, sounds like it ain't broke--so you have no reason to fix it.
