Mine is still super cold (checked it on Saturday it was like... 50F at best) though I did peek inside the cover (after draining the water from the top) and it's crystal clear this year. Last year the cover ripped during the winter and ruined the water but this year it's beautiful looking inside.
I did have an issue I never posted about on here where a piece of nut sedge grew and broke through my liner last august and I repaired the liner (followed the advice I saw on here about injecting roundup in the sand/hole it makes) but apparently my repair/patch wasn't strong enough as I noticed a couple of inches of water have leaked out.. it's not a lot, but it's below the skimmer (and above the return). No water anywhere at all around the pool that I can see so I'm 100% positive my patch failed me over the winter...
