This is my first winter with an inground pool and just about every ounce of me is skeptical that my pool will survive till Spring without some form or damage even though, to the best of my knowledge everything was winterized properly. (Eternal pessimist) It has been unusually cold here even for NC Kansas in the past month or so except for the past 5 days.
We have been having high's in the 40's and even hit 50 yesterday! Regardless, the mild temps tempted me to lift off a corner of the cover to inspect the pool and the chlorine floater level. Much to my surprise the floater was frozen solid amid a 2" layer of ice that covers the entire top of the water surface.
1. Should I be concerned?
2. How long will it take this type of ice to melt with high's in the 40's and 50's?
3. Can this ice crack my fiberglass pool?
My water level is just even with the bottom of the skimmer flange. (the rectangular part that surrounds the opening of the skimmer.) It is not up into the skimmer yet.
