Pools are not abundant where I live and I know of no one who covers their pool in the winter. I fully intend to get a safety cover - to protect our pups in the winter and keep too many Disney character suicides (i.e. not having woodland creatures hop on in) from happening. Out of curiosity as a "newbie":
1. Do you cover your pool? If so, is it more for safety or cleanliness? How "clean" does it keep your pool over non-swim season (i.e. how much easier does it make pool opening?)?
2. Is there anything you can do to keep a pool "healthy" in winter? Where we live, it is nothing to see pools freeze. While researching our build options, we visited a friend's pool in December and it was frozen hard enough their dogs could walk on it (no cover) and there were these green, fuzzy looking masses on the bottom of the deep end. Is that just something you can't prevent and have to deal with every spring or is that some sort of lacking in pool maintenance?
As always, thanks for generous answers to "dumb" questions.
