AV8TOR,
I am in El Paso TX, If I leave my Solar Cover on year round, I have found it does not last that long, I would have to replace it yearly, So this winter I deceided to leave the solar cover off during the non swiming dates, Late Oct to beginning of March, that way I figure that I should get at least 2 yrs out of the solar cover. I have found that leaving the cover on during winter has NO advantages, once the water hits 50 degree, clorine use is minimum, so far as the blowing dust, well if you have the cover on it eventually ends up in the pool anyways, to get the most out of your solar cover is to use it when it is the swimming season. Just my opinion.
