I would say your numbers are perfect! I wouldn't touch the salt right now. Cold weather reduces the conductivity so your salt cell thinks the salt level is lower than it really is. Running a higher salt level in cold weather will put less strain on the cell when it operates. Probably a moot point since most SWGs will cut off in the neighborhood of 55 deg to protect the cell.
Now, the trick will be to maintain these numbers during the blistering heat of July and August!It shouldn't be that hard at all!

Thanks waterbear. Does the cold temps actually affect clarity or is it my imagination? Afterall a glass of ice water is as clear as tap water but looks so much more refreshing.
