Boy, the temperature was VERY refreshing to swim in last night!

Covering at daytime, removing at night… That’s what I did yesterday, and temperature worked out great. Only increased a degree over the day, and I didn’t get the cover on until 11am… And that was with chiller off of course. Can leave chiller on, and [CoolGuard™ Ultra] can hold steady temperature with minimal use.

Boy, the temperature was VERY refreshing to swim in last night! Normally, even with the chiller on, it can’t compete with the temperature increase from the sun.
