Kiddo and I brushed all the water and gunk to the skimmer and got it cleaned up. It was kinda dirty from dust settling on it anyway.
It does help to retain heat, though! I've gone from low 50s to 62 yesterday in about a week. I do wish I'd have gotten a blue one, because with the "clear" one I agree the blue ones look better! The replacement will be blue, whenever that is necessary.
