I opened my pool today and all went good- no leaks, no air and moderate leaf junk.
Water is 52%, but it was frozen just a couple of weeks ago. I actually fell in for the first time testing how thick the ice was - a first for me.
I try to open early (normally April 1st) as we start using the hot tub and will heat for a weekend if it warms up.
Will be opening a few more pools this week and next, so now we just need some warm weather.
Believe it or not I have not covered my pool the past couple of years as I like to keep an eye on the water or ice level - in fact a month or so ago it warned for a couple of days and I drained out another 6 inches of water.
Anyway we do have some weather left, but I do have freeze protection and a back up generator so I not worried --- but I do think it takes a pretty hard freeze > 20 for a day or two to break a pipe, but that's just my experience.
Shocking and running pump now and just need to get cleaned up and the water balanced.
Anyway hope some more people up north and Canada start opening soon. I think its about time....
